In our Application Insights logs for Azure Functions there are a lot of warnings with the message:
The Dashboard setting is no longer supported. See https://aka.ms/functions-dashboard for details.
We build our Azure resources using Terraform, and since our Function Apps target the "~4" runtime version we don't add the AzureWebJobsDashboard setting to our Function's Application settings. (According to the docs: The AzureWebJobsDashboard setting is only valid for apps that target version 1.x of the Azure Functions runtime.)
I was therefore surprised to find the AzureWebJobsDashboard setting with a value in the Azure portal. Any idea how it got there?
I deleted the setting manually in the portal for four of the apps we have running, and the logged warnings went away - however, the setting reappeared in one of them after a little while Is there any way to make sure the deletion is permanent?
Edit: I tried deleting the setting manually for four new apps - making sure to save the changes, and the setting reappeared in two of them after some hours.
Edit2: After 1-2 days the setting is back in all eight apps.
