retry_after.py

<@U080UTBKV19> am I remembering correctly that you asked this question?

Ok ! Thank you very much that is exactly this :slightly_smiling_face:

But that means you don’t raise an exception

You need to catch your exception and then return the AwaitingRetry state

Huh, wait actually looks like there’s even more functionality than I remembered: <https://docs.prefect.io/v3/develop/write-tasks#custom-retry-behavior>

&gt;  The `retry_condition_fn` argument accepts a callable that returns a boolean. If the callable returns `True`, the task will be retried. If the callable returns `False`, the task will not be retried. The callable accepts three arguments: the task, the task run, and the state of the task run. The following task will retry on HTTP status codes other than 401 or 404:

Hmm, although that doesn’t let you control the retry delay.

Yeah I guess this time you’d need to wait someone using time.sleep
