Prefect Community

Hi! I have many prefect flows and deployments in prefect cloud. Yesterday and today I received the following error for many tasks:

&gt;  Crash detected! Execution was interrupted by an unexpected exception: PrefectHTTPStatusError: Client error '429 Too Many Requests' for url <https://api.prefect.cloud/api/accounts/.../workspaces/.../task_runs/.../set_state>
&gt; Response: {'detail': 'Orchestration API rate limit reached'}
&gt; For more information check: <https://httpstatuses.com/429>
Yesterday, before the flow run, I made a new deployment. Is anyone having similar errors?? Thank you!!

Hi <@U01KFB0040G> :wave: Looks like you hit your plan <https://docs.prefect.io/latest/cloud/rate-limits/|rate limit>. If you are on the free tier, you can increase your limit by upgrading to the pro tier. It’s worth noting that the Prefect client attempts to retry any rate limited request several times. If you enable debug logging, you can see the retries happening.

Oh thank you! I didn't notice the rate limit per minute. I will check it, thank you!

It is strange <@U02JKLM1C2K>, because the limit says 400 calls per minute. I checked the event feed, and when I got the 429 it says about 250 events. Is this the correct way to check the number of API calls? Thank you!
