Request error in a PUT method

I made a call REST with PUT method. I used a maping for request. but I face this error message:  unexpected character ('<' (code 60)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false')  at [Source: (org.apache.http.conn.EofSensorInputStream); line: 1, column: 2]   I have used '<’ nowhere

Is your application making a REST PUT to an external service?

If it is try turning the log level of REST Consume to TRACE in the console. That will show you the request being sent and response being received. I suspect it could be the service returning the ‘<’ in its response.
