self.attempt_number: int = 1

attempt_number should be set to 1
the stop_after_attempt is checking current_attempt >= max_attempt
As aresult we are retrying 1 less time than max_attempt

In case max_attempt = 1, there are no retries.
The condition for stop after retry should be ">" and not ">=" OR attempt_number should be set to 0

I believe the "max attempt" is not for retries, but for all attempts.

Ie. stop_after_attempt(1) means no retries, because it gives up after the first attempt.
