@Yanyu Chen I'm glad to see you were able to resolve your issue.

Thanks for posting your solution so that others experiencing the same thing can easily reference this. Since the Microsoft Q&A community has a policy that the question author cannot accept their own answer, they can only accept answers by others, I'll repost your solution in case you'd like to Accept the answer.

Issue:
You are facing an issue with your Timer Triggered Azure function, which is failing to update the timer trigger status and you get the error Azure.Storage.Blobs: Service request failed with HTTP error 500.

Resolution:
You deployed your function to the function app directly, it works fine on the cloud. So probably the issue could be due to the VS code version or your local system.
