The error message indicates that a REST API request failed with a 400 Bad Request status. Specifically, the response body states:
"Phone No. must not contain letters in Customer No.='C-009999'"This suggests that the Phone_No field contains invalid characters (e.g., letters or extensions such as "x4321"), which the destination system does not accept.
The REST service returned a status code that is not 20x - i.e. not OK - Status code received: 400 Bad Request Response body: {"error":{"code":"Internal_ServerError","message":"Phone No. must not contain letters in Customer No.='C-009999'. CorrelationId: 5a041048-ede7-4d6a-9193-3ef1508b5454."}} Data Sent to REST service: {"Phone_No":"732-532-4444 x4321"} Error on connection NAVODATA001.
