Mac:

    {"error":{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: Model with id=\"test-model-id\" already exists;"}],"type":"action_request_validation_exception","reason":"Validation Failed: 1: Model with id=\"test-model-id\" already exists;"},"status":400}
