It looks like you're receiving an error message indicating that the JSON request is invalid. One potential issue could be that the JSON is not properly formatted or that a required field is missing. I would recommend checking the API documentation for the CyberSource endpoint you're trying to reach and verifying that the request body and headers match the specified requirements. Additionally, double-checking the JSON formatting and making sure all required fields are present in the request body might be helpful. If the problem persists, you might want to consider reaching out to CyberSource support for further assistance.

The TransientTokenJwt field may be the cause of the problem. According to the CyberSource documentation, the Transient Token JWT must be included in the API request's Authorization  header. It could be worthwhile to double-check that the request headers contain the JWT and that it is being transmitted in the appropriate manner.
