@Marvin I am attempting to run an AWS ECS push work pool with an EC2 back end. I am getting this error Flow run could not be submitted to infrastructure: Failed to create ECS task run: [{'arn': 'ARN_REMOVED', 'reason': 'ATTRIBUTE'}] What should I be looking for here? Is there any way to get a better error message?

The error message you're encountering is related to an issue with ECS task attributes. Here's what I found: 1. Potential Issue: ECS tasks are groupings of containers running within an ECS Cluster, with their behavior determined by the task definition. The error you're seeing might be due to missing or incorrect ECS task definition attributes. Ensure that all required attributes are correctly specified in the ECS task definition. More info: Prefect AWS ECS Guide and another relevant page is Prefect AWS guide. 2. Resolving the Error: Ensure you have the proper setup: - An ECS Cluster for hosting both the worker and the flow runs. - A VPC configured for your ECS tasks. - ECS task definitions with all required attributes correctly specified. - For EC2, verify that the EC2 instances have the necessary IAM roles and permissions. 3. Enhanced Error Messaging: Currently, the provided error message isn't very detailed. You can enable detailed logging in AWS ECS to get more information about what's going wrong. Check your ECS task logs in AWS CloudWatch. If you continue to face difficulties, you might find more detailed guidance and troubleshooting steps in the Prefect documentation. I hope this helps you identify and resolve the issue. If you need further assistance, please let me know!
