429 not being restarted for stream requests #1195
Description
Long story short
Hi, I am not sure if I am not sure if this is an actual bug or if I am missing something.
I am getting the error you can check in the logs section.
In my mind, as this goes through the check_response and is identified as a APIClientError, this should be caught by the retry logic and try again after some backoff, as it would make sense for a 429.
Is the retry mechanism missing this, or did I get something wrong?
If there is an actual bug, I would be happy to contribute.
