boto.exception.InvalidInstanceMetadataError: Expected a dict type of credentials instead received an empty string
You can set the 'metadata_service_num_attempts' in your boto config file to increase the number of times boto will attempt to retrieve credentials from the instance metadata service.

Obviously a boto error, but if we can make something at simpleflow level..
