how retry flow programmatically works in azure function

Question

Need some clarification -- As mentioned in the official doc that we have to re-throw the exception during the retry flow, so I want to understand after re-throwing the exception where that exception handle - in the same block of code from where it throws or in some other block created by retry mechanism.

Answer 1

@Shweta This caught by the Azure Functions Runtime which triggers the retry. The docs do mention that uncaught exceptions would trigger a retry. To quote the retry policies doc,

A retry policy is evaluated whenever an execution results in an uncaught exception. As a best practice, you should catch all exceptions in your code and rethrow any errors that should result in a retry.
