@frostebite any update on this? I'm struggling to get the AWS permissions correct. For example, these are the two errors I got and their corresponding permissions I added to resolve them:

Event Status	AWS Permission
No export named game-ci:ECSTaskExecutionRole found. Rollback requested by user.	AmazonECSTaskExecutionRolePolicy
No export named game-ci:CloudWatchIAMRole found. Rollback requested by user.	CloudWatchEventsFullAccess

I'm now getting No export named game-ci:EfsFileStorageId found. Rollback requested by user. and have not been able to figure out what Permission it is tied to.

Edit:

Actually I'm wrong about my table above. If I rerun my job it's randomly throwing one of those three errors. Seems like I was just thinking I was resolving by adding the permissions. I'm a bit lost then as to what's needed to make this work then. Any pointers would be appreciated.
