I’m also getting these a LOT since some time. Was anything changed? I’m also uploading directly through the API and retrying all 429 (getting a lot of 429s). What should a well behaved client do other than retry?
And is it the correct behavior that the deploy just gets stuck at “uploading”?
Here is a thread with more info: API Uploads (files only): Deploys get stuck in state: "uploading"
