Hi Community, We need help with Prefect agent setup. We have hosted Prefect server in EC2 instance and created prefect agent in ECS Faregate. We are using docker image as “prefecthq/prefect:2.10.8-python3.10”. We configured environment variables "‘PREFECT_API_URL’ , ‘PREFECT_CLOUD_API’ ‘PREFECT_LOGGING_LEVEL’: ‘INFO’,‘AWS_RETRY_MODE’‘adaptive’,‘AWS MAX ATTEMPTS’‘10’ while creating ECS Fargate Agent Service and running ""prefect agent start -p default-agent-pool -q default"" command through command line. In ECS Fargate while running services and task we are getting below error. If someone can point out which environment variable setup missing then it help us to complete setup. Error logs : Agent started! Looking for work from work pool ‘default-agent-pool’… Failed the last 3 attempts. Please check your environment and configuration.
