I have migrated from in-process function to isolated worker process(.net6 to .net8).
Before migration I was not getting any timout exception. On lower environments as well app didnt get any timeout and testing was successful. But on production getting “Microsoft.Azure.WebJobs.Host.FunctionTimeoutException”.

I haven’t done any code logic changes, just code changes for upgrading. No changes done in host.json
I can increase the timeout value as a solution but I wanted to know why this behaviour has happened?

Please forgive my question structuring.

I have searched the net for such behaviour of function app but not getting anything specific to my question
