Fax callback API with incorrect Content_Type

GerardZ

ID edm.fax.dev@prudential.com is configured at the account level for a callback API with application/json format. This functionality is working.

However, for job_id xsi-1507269286, the content_type of the callback api request payload is text/xml;charset=UTF-8, which is causing the callback response to not be processed.

The document attached are part of xsi-1507269286 is "pdf" but the actual content of the pdf is invalid (not a valid pdf). In this case, the expectation is for the callback api request payload to be application/json containing an error status and gamma code.

Could you please investigate why the content_type of the callback API is being set incorrectly in this case?

Thanks
