Getting Server Error - There was an unexpected error in the request processing azure

Question

I started getting "

Server Error - There was an unexpected error in the request processing azure" randomly in azure function apps after Aug 22, 2023.

I am unable to see any description of these errors in logs.

My scenario is :

• Load is getting distributed to two Azure Function Apps deployed on different regions (US Central and US East) using Azure Traffic Manager.
• Both the function apps are getting down at the same time with the above mentioned error.
• No details regarding the error in logs.
• Need help with troubleshooting as it seems to be from Azure end.

I see that you are facing an issue with your Azure Function Apps, which are deployed on different regions (US Central and US East) and are getting down at the same time with the error message "Server Error - There was an unexpected error in the request processing azure." You are unable to see any description of these errors in logs and seeking help with troubleshooting as it seems to be from Azure's end.

Please follow the below action plans for now:

1. Could you please enable the Application insight logs for the FunctionApp and check if there are any invocation exceptions. You can enabled the AppInsights as explained here.You can enabled the AppInsights as explained here.
