SAP HCI - Content Modifier query

Hi SDNites,

I have populated XML is Content modifier and connected this step with the message mapping. It gets deployed with error and have obtained the below message,

Content Modifier may not pass Xml message to Message Mapping. Message Mapping supports Xml input only.

Also it is deployed but I cannot see in the monitoring so I believe it because of the message mentioned above. Can you please guide how can I resolve the above.

Regards,

Abhi
