Hello, We're running on Prefect 2.7.8. Up until today our Prefect deployment CI/CD job was working just fine. We haven't performed any recent version upgrades to our environment or our Python dependencies. This error began to occur a earlier today:
Copy code
httpx.HTTPStatusError: Client error '422 Unprocessable Entity' for url '***/deployments/'
For more information check: <https://httpstatuses.com/422>
A version upgrade to Prefect 2.7.9 appears to have solved the issue. However, it's strange that our CI/CD for deployments started failing seemingly out of no where. Does anyone know the cause of this issue?

I am getting the same issue, I really have to upgrade?

Upgrading seems to have resolved it for us.

Hi all, Prefect has fixed this for 2.7.8 and you should not be experiencing the 422 error anymore.

I seem to be getting a similar or the same error on 2.7.9 and 2.7.10
