@Marvin - running an ecs work pool, when running a task container it exits with 1 code. the following task is being executed, which i imagine it's missing a run id in the environment - i would assume this is being injected but I do not see it in the task definition

It seems like you're experiencing an issue where a task container in your ECS work pool is exiting with code 1, possibly due to a missing run ID in the environment. This run ID is crucial for Prefect's
flow-run execute
command to function properly. Here are a few insights and suggestions based on the gathered information: 1. Runtime Context: Prefect uses a runtime context to manage execution details, including the run ID. This context should be available during the execution of flow runs. You can mock runtime values for testing using environment variables, as documented here. 2. ECS Task Definition: Ensure that your ECS task definition is correctly set up to inject necessary environment variables. Prefect typically manages this, but if there's a misconfiguration, it could lead to missing environment variables. 3. GitHub Issues: There are no direct issues related to your specific problem, but other users have faced issues with Prefect's ECS integration, such as import errors or runtime errors in specific setups. Reviewing your ECS configuration and Prefect version compatibility might help. 4. Documentation: You can refer to the work pools documentation for more details on managing and configuring work pools, which might provide additional insights into resolving your issue. If the problem persists, you might want to check Prefect's deployment logs or reach out to the Prefect community for more tailored support.

@Marvin - these are the logs. it appears the flow run id is available but when building the image it's not available

It seems like the issue might be related to how environment variables, particularly the flow run ID, are being handled during the ECS task execution. Here are some insights and suggestions based on the documentation: 1. ECS Task Definition: Ensure that your ECS task definition correctly specifies the environment variables needed for the Prefect flow run. The flow run ID should be included in the execution environment of the ECS task. You can refer to the ECS Guide for setting up ECS tasks with Prefect. 2. Image Build and Execution: If the flow run ID is available during execution but not during the image build, ensure that the environment variables are correctly set in the ECS task definition and not just during the build process. The Managed Execution Guide suggests using the official Prefect Docker image or configuring your own with the necessary environment settings. 3. Role and Permissions: Make sure that the ECS task role has the necessary permissions to access resources, such as pulling images from ECR and logging to CloudWatch. This might affect how the task is executed and whether it can properly access the environment settings. If these suggestions don't resolve the issue, consider checking your ECS configuration for any discrepancies or reaching out to the Prefect community for more specific guidance.
