anonymous user ,
Thanks for posting this question in the Microsoft Q&A forum.
This appears to be a sync trigger issue. First, make sure you have enabled the "Always On" setting under the Configuration section. Since you have a working and non-working environment, try to compare the app settings of both the environment and make sure the dev function are identical to the working Function app.
Also check the Diagnose and Solve problems blade. This section has a detector called "Function app down and reporting errors", run this detector to see if there are any problems with the Function app.
I hope this helps!
