HTTP Error 502.5 - Process Failure after publishing to Azure

[hakonamatata]

Hi

I tried to publish the latest version of this project to Azure. When I create a new web app and publish for the first time, this works perfectly.

But as soon as I build the project again locally and attempt to update the web application in Azure by publishing again, I get this error:

Error:

HTTP Error 502.5 - Process Failure

Common causes of this issue:
The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port

Logging in Azure only shows:

System.ApplicationException: The trace listener AzureBlobTraceListener is disabled. ---> System.InvalidOperationException: The SAS URL for the cloud storage account is not specified. Use the environment variable 'DIAGNOSTICS_AZUREBLOBCONTAINERSASURL' to define it.
   at Microsoft.WindowsAzure.WebSites.Diagnostics.AzureBlobTraceListener.RefreshConfig()
   --- End of inner exception stack trace ---

I also tried to "attach debugger" in Visual Studio, but then I only get:

Unable to find a process called dotnet with arguments .\Asp2017.dll. The process may still be starting, please try again.

I have made some changes to the application, but that is mostly html and css, but I will try to publish a unchanged version of this project and see if the same happens.
