Prefect Community

Hi, we have a self-hosted EC2 setup with ECS worker pool configured. We have run into an issue where all our flows are moving into `Crashed` state. Upon checking our prefect-worker-service in ECS cluster, we see this error. Any idea what's going on? It was working just fine. Thanks!
