I am trying to set up an om_http output. I get the response of ERROR HTTP response status is not OK: 400 Bad Request

I need to trouble shoot what message I am actually sending. Is there an easy way to see what message is sent?

This is my in/out config. <Extension _syslog> Module xm_syslog </Extension> <Extension _json> Module xm_json </Extension> <Input in> Module im_file File '<scrubbed>/data.json' Exec $message = to_json(); </Input> <Output out> Module om_http URL <scrubbed> HTTPSCAFile <scrubbed> HTTPSCertFile <scrubbed> HTTPSCertKeyFile <scrubbed> ContentType application/vnd.kafka.v1+json </Output> <Route 1> Path in => out </Route>
