Hello! I'm trying to deploy Metaflow to AWS Step function and I want to use Fargate. I used CloudFormation to do it. Everything seems to work fine but I don't understand what to do with this:

AWS Batch job error:
    No AWS Fargate task execution IAM role found. Please see <https://docs.aws.amazon.com/batch/latest/userguide/execution-IAM-role.html> and set the role as METAFLOW_ECS_FARGATE_EXECUTION_ROLE environment variable.

Should I create IAM role ? Or just copy from somewhere ?

it seems you might have an older version of

boto3

- can you do

pip install -U boto3

Updated. Still the same. Maybe I used the wrong ARN. How can I check this?
