Error handling in DXC
Hi Francisco,
If you are using the Azure environment then try with the below setting in the web.config on the DXC environment.
<customErrors mode="Off"> </customErrors><applicationSettings globalErrorHandling="Off" ....>
Thanks,
Sanjay

Hi Sanjay,
It did not work. I still see the standard message "The page cannot be displayed because an internal server error has occurred."
Regards.

Hi Francisco
Have you also allowed "Detailed error messages for troubleshooting" for Everyone in Permissions for Functions? Your screenshots doesn't show.

Hi Stefan,
Yes, I did. It still shows me the generic error "The page cannot be displayed because an internal server error has occurred.". It looks like the detail error message does not work on DXC.

I know that it works in DXC, having worked on sites where I could retrieve YSOD details in all DXC environments.
Do you have anything in Global.asax that overrides the error handling?

I only have this code:
protected void Application_Error()
{
var ex = Server.GetLastError()?.GetBaseException();
Log.Error(string.Empty, ex);
}
It's weird because the error message is working properly on my local environment.

Log.Error(string.Empty, ex);

What if you remove that method? In DXC you won't need it anyway, since Application Insights automatically logs unhandled exceptions from it's HTTP Module.
Hi Francisco,
You need to trace the error log on the Azure portal. Please follow the below steps and try to investigate.
- Login to Azure Portal
- Goto--> App Service
- MONITORING
- Diagnostics logs
- Application Logging (ON) --> Information (Choose level) --> SAVE
- Detailed error message (ON) --> Save
- Log stream
- Application logs (loading...)
- Maybe need to refresh site URL to trace the Application log if shows loading...
- Copy the generated text, save as HTML and the run on the browser window.
- Diagnostics logs
- MONITORING
Hopefully, you will get the actual error and then fix it.

Hi Sanjay,
I threw the exception on purpose to validate the content of the error page on integration. I don't want to create a custom 500 error page. I just want to use what Episerver has out of the box.

Hi Francisco,
What do you have configured for the web server? I mean section <system.webServer> <httpErrors> and there the errorMode attribute.
By default that is DetailedLocalOnly so you should set it to Detailed if you want to see detailed errors from server (in addition to setting the asp.net error handling in system.web customErrors mode="Off").
(and also check what you have in your config transforms for the environment you don't see detailed exceptions)

Hi Antti,
I have changed the configuration according to what you said, but I am still not able to see the custom Episerver error page. This is my configuration:
Now I see something like:
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has occurred.

I'm fairly certain that clicking in Admin Mode System Settings will only update one node's web.config file and should never be used other than to look at stuff.

Hi, I have activated the Error handling in Episerver CMS to "Activate for all". It is working correctly in my local environment, but it is not in INTEGRATION. I always get the error: "The page cannot be displayed because an internal server error has occurred."
Actual result:
Expected result:
Does anyone know how can I take advantage of this feature in DXC?
