Hey All, 2 of the prefect instances we manage with ECS started to fail all of their flow runs yesterday afternoon. Im looking at the logs and seeing this error, has anyone else seen this?

Yes, this occurs when the Prefect version of your agent is too far ahead of the Prefect version of your flow run containers. If you haven't upgraded your agent version recently, it could be inadvertently upgrading its version due to dependency checking on additional packages like prefect-aws.

Yeah okay thanks for the pointer @Kevin Grismore. It looks like the agent task was redeployed yesterday for some reason and that installed a new version of prefect-aws
