In SAP PO Rest adapter issue "JSON RESPONSE: Input is not valid JSON at character 25 "

Hi

we have developed 6 interfaces which is proxy to REST scenarios of which 3 interfaces are working fine in the 4 interface i am getting the error

SAP PO REST ADAPTER JSON RESPONSE: Input is not valid JSON at character X (???) .

In DEV all the interfaces are working fine only in case of PROD i am getting the issue.

Please provide resolution.

Already we have implement the resolution provided in the note AP note 2435422 New Feature: Binary data handling from REST Adapter, binary data can also now be handled in the Sender and Receiver REST Adapters.

where we have added one extra header parameter (application/octet-stream) but still error persist.

Thanks,
