Oracle Integration-OIC - Version 18.2.5 and laterInformation in this document applies to any platform.
Goal
When using the REST Adapter to POST to a 3rd party service which does not require a request payload, the REST service responds with a HTTP 411 / Length Required / Content-Length is missing error response.

How can this be resolved when the Content-Length HTTP header is grayed out, and cannot be selected in the REST Adapter Wizard ?
