Uncaught exception rendering console view #3121

Comments

hwalker928 commented Feb 23, 2021

Background (please complete the following information):

• Panel or Daemon: Not 100% sure
• Version of Panel/Daemon: v1.2.2
• Server’s OS: Ubuntu 20.04, but most likely all
• Your Computer’s OS & Browser: Windows 10 Firefox, doubt it’s a OS issue as it also occurs on Mac’s.

Describe the bug
While switching between servers, or tabs (backups, schedules) and then back to console, you may occasionally get a «An error was encountered by the application while rendering this view. Try refreshing the page.». Refreshing seems to fix it 100% of the time, but it is extremely annoying. This is not host or device specific, as I have had this issue on multiple different panels, devices and even locations. The console error can be found attached as an image, as well as the rendering error.

To Reproduce
Steps to reproduce the behavior:

1. Go to a server or to console from another tab.
2. See error

Expected behavior
For the console to show without needing a refresh.

The text was updated successfully, but these errors were encountered:

Возникла ошибка «The script encountered an error and will be aborted. »

Рассказываем, что означает сообщение и как убрать ошибку.

«The script encountered an error and will be aborted. To view extended error messages, enable this feature in .settings.php.» — в скрипте обнаружена ошибка, его действие прекращено. Посмотреть детальную информацию о ошибке можно в файле «.settings.php».

В административной панели 1С-Битрикс перейдите по пути: Контент → Структура сайта → Файлы и папки → bitrix.

Найдите в списке «.settings.php», раскройте меню (1) и перейдите к редактированию файла как PHP (2).

Перейдите к строке ‘debug’ => ‘false’. Замените false на true. Появится значение ошибки.

Наиболее частая проблема — закончилось свободное место на диске.

Как решить ошибку

Для решения можно удалить неактуальные файлы или расширить место на тарифе.

Как проверить свободное место

Сперва стоит посмотреть в панели управления услугой, какие ненужные файлы используют место. Для виртуального хостинга и сервера проверка немного отличается.

На виртуальном хостинге вы можете использовать Статистику для просмотра каталогов и файлов, которые зря занимают место.

На сервере можно использовать несколько вариантов:

Общий вариант для обеих услуг — посмотреть занятое место с помощью утилиты ncdu.

Как удалить неактуальные файлы

Если действительно место заняли устаревшие локальные копии 1С-Битрикс или кэш, удалите их из панели управления хостингом. Перейдите в Главное (1) → Менеджер файлов (2). Откройте каталог с файлами (3):

• копии хранятся в каталоге /backup/, перейдите в него по пути www/ваш сайт/bitrix/backup,
• кэш — в каталоге /cache/, перейдите в него по пути www/ваш сайт/bitrix/cache.

Выделите ненужные файлы (4) и удалите их (5).

Как расширить место на тарифе

Если место занято нужными для работы файлами, стоит увеличить размер диска. Для тарифов возможности разные.

If possible, please delete the project Cache from the below location:

C:Program FilesMicrosoft Visual Studio 14.0Common7IDEProjectTemplatesCache

C:Program Files(x86)Microsoft Visual Studio 14.0Common7IDEProjectTemplatesCache

Then run commend line: «devenv.exe /setup» to re-build the cache.

C:Program FilesMicrosoft Visual Studio 14.0Common7IDEdevenv.exe /setup

Please also run your VS in safe mode, so we could know that whether it is related to the add-ins or extension tools:

There is no «Microsoft Visual Studio 14.0″ folder in » C:Program Files «, so I only deleted the folder:
C:Program Files (x86)Microsoft Visual Studio 14.0Common7IDEProjectTemplatesCache

I opened cmd and run the following line (both with/without admin rights)
«C:Program Files (x86) Microsoft Visual Studio 14.0Common7IDEdevenv.exe» /setup

A message box by Microsoft Visual Studio jumped out, saying «The operation could not be completed»

>>A message box by Microsoft Visual Studio jumped out, saying «The operation could not be completed»

You would open the VS’s command line window.

CD to the VS setup folder, and then run the command line:

It didn’t work either.
I typed cd setup and press enter, typed devenv.exe /setup and press enter. It gave me «The operation could not be completed» message again.

Thanks for your friendly response.

What is your windows Environment, 32 bit or 64 bit? Do you install the VS in the default path like C:Program Files(x86)Microsoft Visual Studio 14.0Common7(64 bit windows)? Maybe you could run the command prompt as the admin, check it again.

I test it in my side:

(1) Delete the project cache files.

(2) Run the Developer Command prompt as the admin, run the command line, it would re-create the project cache file.

Like my previous reply, do you run your VS in safe mode? Is it still has this issue in safe mode?

Please also open your VS as the admin, check the result.

Or you could repair your VS, please also install the update 1.

If still no help, maybe we could collect the detailed VS setup logs.

Please use http://aka.ms/vscollect to gather the VS and .Net Frameowrk installation logs. After using it, you will find vslogs.cab from %temp% folder. Please upload the file to Onedrive and share the link here .

The message is still showing even:
1) After deleting the project cache files and recreate them using Developer Command prompt as admin.
2) In safe mode.
3) When opening VS as admin.

I am using the Update 1, repair and uninstall cannot fix it.

I didn’t find vslogs.cab, but I found vslogs.zip

I think the problem happened when I did a system restore to when I haven’t installed it.

If possible, please remove all extension tools under Extensions and updates windows except the default tools.

>>I think the problem happened when I did a system restore to when I haven’t installed it.

If so, maybe you could run the windows updates, and restart your machine.

If there are some setup files in your local machine even if you uninstall it, I suggest you clean up them using the command line.

The detailed steps:

Download the setup application you used to originally install Visual Studio 2015. If you installed from media, please insert that media.
2.Open a command prompt.
a.Click Run on the Start menu (Start + R).
b.Type cmd and press OK (Enter).
3.Type in the full path to the setup application and pass the following command line switches: /uninstall /force
Example: D:vs_xxx.exe /uninstall /force
4.Click the Uninstall button and follow the prompts.

And then re-download the latest VS version: VS2015 community with update 2:

Is there an existing issue for this?

• I have searched the existing issues before opening this issue.

Current Behavior

When viewing opening a link directly to a schedule, the error «An error was encountered by the application while rendering this view. Try refreshing the page.» is shown.

Expected Behavior

The schedule should be viewed and React should not break.

Steps to Reproduce

Go to a schedule, copy the link and paste it into a new tab.

For example, opening https://panel.example.com/server/27aecb4d/schedules/1 will break React from showing any server page unless you go back to servers and choose a new one.

Наиболее частая проблема — закончилось свободное место на диске.

Как решить ошибку

Для решения можно удалить неактуальные файлы или расширить место на тарифе.

Как проверить свободное место

Сперва стоит посмотреть в панели управления услугой, какие ненужные файлы используют место. Для виртуального хостинга и сервера проверка немного отличается.

• На виртуальном хостинге вы можете использовать Статистику для просмотра каталогов и файлов, которые зря занимают место.

• На сервере можно использовать несколько вариантов:

• посмотреть статистику контента,
• воспользоваться функцией df -h.

Общий вариант для обеих услуг — посмотреть занятое место с помощью утилиты ncdu.

Как удалить неактуальные файлы

Если действительно место заняли устаревшие локальные копии 1С-Битрикс или кэш, удалите их из панели управления хостингом. Перейдите в Главное (1) → Менеджер файлов (2). Откройте каталог с файлами (3):

• копии хранятся в каталоге /backup/, перейдите в него по пути www/ваш сайт/bitrix/backup,
• кэш — в каталоге /cache/, перейдите в него по пути www/ваш сайт/bitrix/cache.

Выделите ненужные файлы (4) и удалите их (5).

Как расширить место на тарифе

Если место занято нужными для работы файлами, стоит увеличить размер диска. Для тарифов возможности разные.

Увеличивается место на услугах по-разному: на виртуальном хостинге за пару кликов, на сервере с помощью наших специалистов.

Как контролировать место

На виртуальном хостинге пока что реализована ручная проверка, на серверах можно подключить систему RED.Monitoring. Она оповестит, когда места останется слишком мало. А в критической ситуации к решению подключится наша поддержка: удалит устаревшие копии 1С-Битрикс или свяжется с клиентом напрямую.

however, i don’t even have any line 121 in app/views/dashboard/index.html.erb:121 as the code finishes before that at line 119.

How can I find this syntax error?. any and all ideas will be welcome. my production server config is shown below

# Reading Error Logs

If you ever encounter an unexpected error with the Panel the first thing you will likely be asked for is the logs.
To retrieve these, simply execute the command below which will output the last 100 lines of the Panel’s log file.

# Parsing the Error

When you run the command above, you’ll probably be hit with a huge wall of text that might scare you. Fear not,
this is simply a stacktrace leading to the cause of the error, and you can actually ignore almost all of it when
looking for the cause of the error. Lets take a look at some example output below, which has been truncated to
make this easier to follow with.

The first thing you’ll want to do is follow the chain of numbers up until you find #0, this will be the function that
triggered the exception. Right above line 0 you will see a line that has the date and time in brackets, [2018-07-19 00:50:24]
above for example. This line will be the human readable exception that you can use to understand what went wrong.

# Understanding the Error

In the example above we can see that the actual error was:

From this error we can determine that there was an error performing a file_put_contents() (opens new window) call, and the error was
that we couldn’t open the file because permissions were denied. Its okay if you don’t understand the error at all, but
it does help you get faster support if you’re able to provide these logs, and at least find the source of the error.
Sometimes the errors are pretty straightforward and will tell you exactly what went wrong, such as a ConnectionException
being thrown when the Panel can’t connect to the Daemon.

# Utilizing GREP

If you’re trying to go through a bunch of errors quickly, you can use the command below which will limit the results returned to only
be the actual error lines, without all of the stack traces.

# Transfer Exceptions / XHR Poll Error

If you are seeing errors similar to the examples below, chances are there is some networking related issue, or you
just don’t have a required service running.

# Example Errors

• «We were unable to connect to the main Socket.IO server, there may be network issues currently. The panel may not work as expected.»

• «A TransferException was encountered while trying to contact the daemon, please ensure it’s online and accessible. This error has been logged.»

# Basic Debugging Steps

• Ensure you have AdBlock disabled or whitelisted for your Panel and Daemon domains.

• Check your browser’s console by pressing Ctrl + Shift + J (in Chrome) or Cmd + Alt + I (in Safari). If there is
  a red error in it, chances are that it will narrow down the potential problem.

• Make sure if the daemon is properly installed and the active configuration matches the configuration shown under
  Admin -> Node -> Configuration in the Panel.

• Check that the Daemon is running, and not reporting errors. Use service wings status to check the current status of the process.

• Check that the Daemon ports are open on your firewall. The Daemon uses ports 8080 or 8443 for HTTP traffic,
  and 2022 for SFTP traffic.

• Check that the Panel can reach the Daemon using the domain that is configured on the Panel. Run curl https://domain.com:8080 on the Panel server and ensure that it can connect to the Daemon.

• Ensure that you are using the correct HTTP scheme for your Panel and Daemon. If the Panel is running over HTTPS
  the Daemon will also need to be running on HTTPS.

# More Advanced Debugging Steps

• Stop the Daemon and run cd /srv/daemon; sudo npm start to see if there are any errors being output by the Daemon.
  If so, try resolving them manually, or contact us on Discord for more assistance.

• Check your DNS and ensure that the response you receive is the one you expect using a tool such as nslookup or dig.

• If you use CloudFlare make sure that the yellow cloud is disabled for your Daemon or Panel A records.

• Make sure when using the daemon behind a firewall — pfSense, OpenSwitch, etc — that the correct NAT settings to access
  the Daemon’s ports from the outside network are setup.

• If nothing is working so far, check your own DNS settings and consider switching DNS servers.

• When running the Panel and Daemon on one server it can sometimes help if to add an entry in /etc/hosts that directs
  the public IP back to the server. Sometimes the reverse path is also needed, so you may need to add an entry to your
  servers /etc/hosts file that points the Panel’s domain to the correct IP.

• When running the Daemon and Panel on separate VM’s using the same adapter make sure the VM’s can connect to each
  other. Promiscuous mode might be needed.

# Invalid MAC Exception

Sometimes when using the Panel you’ll unexpectedly encounter a broken page, and upon checking the logs you’ll see
an exception mentioning an invalid MAC when decrypting. This error is caused by mismatched APP_KEYs in your .env file
when the data was encrypted versus decrypted.

If you are seeing this error the only solution is to restore the APP_KEY from your .env file. If you have lost that
original key there is no way to recover the lost data.

# SELinux Issues

On systems with SELinux installed you might encounter unexpected errors when running redis or attempting to connect
to the daemon to perform actions. These issues can generally be resolved by executing the commands below to allow
these programs to work with SELinux.

# Redis Permissions Errors

# In case there is any weirdness with parts of the panel

# Daemon Connection Errors

# FirewallD issues

If you are on a RHEL/CentOS server with firewalld installed you may have broken DNS.

restart docker and wings after running these to be sure the rules are applied.

# Database Errors

# DatabaseController.php:142

The database user you are trying to use doesn’t have appropriate grants/has used incorrect password.
