AWS Macie list_findings() errors.

I am attempting to build a lambda (with boto3/python) using the list_findings call. My function is:

response = client.list_findings(
        findingCriteria={
            'criterion': {
                'Job ID': {
                    'eq': ['5e8ff9bf55ba3508199d22e984129be6']
                }
            }
        },
        maxResults=50,
        nextToken='continued',
        sortCriteria={
            'attributeName': 'bucketArn',
            'orderBy': 'DESC'
        }
    )

The Job ID does exist within my Macie console. (And is intentionally 'hard coded' here at the moment however once working will be a variable.). When I attempt to test I receive the below error. Has anyone else ran into this issue? If so how is it corrected?
Response

    "  File \"/opt/python/botocore/client.py\", line 960, in _make_api_call\n    raise error_class(parsed_response, operation_name)\n"
  ]
}

Tried looking at the API documentation at: https://docs.aws.amazon.com/macie/latest/APIReference/findings.html however according to it, none of the fields appear to be required (all show as false). I have also tried it with several variations on the job ID (variable, f string variable, tuple, etc...).
