Hey all, I'm having this error when following the docs (https://docs.metaflow.org/production/scheduling-metaflow-flows/scheduling-with-aws-step-functions#pushing-a-flow-to-production):

Invalid type for parameter containerProperties.jobRoleArn, value: None, type: <class 'NoneType'>, valid types: <class 'str'>

What could possible be the cause?
