@Marvin I get the following error deploying to Prefect3 prefect.exceptions.PrefectHTTPStatusError: Client error ‘422 Unprocessable Entity’ for url ‘http://localhost:4200/api/deployments/’

It seems like you're encountering a

422 Unprocessable Entity

error when deploying to Prefect 3. This error typically indicates an issue with the request payload being sent to the Prefect server. In the context of Prefect 3.x, one common cause could be related to field mismatches in the deployment payload. From my search on GitHub issues, there is a relevant issue here where using certain API calls results in 422 errors due to extra fields such as

infra_overrides

being sent which the server does not recognize. To address this issue, you can: 1. Ensure that your client and server versions of Prefect are compatible. Mismatches in client-server API expectations can lead to errors like this. 2. Double-check the deployment code and ensure that no deprecated or unsupported fields (like

infra_overrides

) are being included in your requests. Unfortunately, I couldn't perform the documentation search correctly due to a technical issue. However, I recommend reviewing the Prefect 3.x deployment documentation to ensure you're following the latest guidelines: Prefect 3.x Deployment Guide. If the problem persists, you might also consider opening or checking current GitHub issues for updates or patches from the Prefect development team.

hi @Avi - can you share the traceback? this sounds like a schema mismatch

I see that the server is 3.0.2 but the client is 3.0.4. Now I am aligning

can you share what the actual mismatch was? was it related to labels?

Here is the entire trace:

aha, thank you!

after aligning it worked
