REST Web Service - Request Logging

Situation:

I am attempting to call a REST Web Service and post some JSON, but i'm getting an error before the call ever makes it to the end point. the error is as follows:

"Processing of the HTTP request resulted in an exception. Please see the HTTP response returned by the 'Response' property of this exception for details."

Any ideas what could be causing this?

Tip:

Try enabling the REST message logging from the System Properties

abpm.webservice.rest.jersey.dumpmessages

Administer > Setup > Application Settings > Update System Properties
Services > Web Service Configuration

Once this is enabled, you should be able to see the REST request being sent in the KernelApplication.log file

- /ServerKernel/logs/applicationlogs
