Unable to include JSON Body with every request

The ‘Body parameters to include with every request’ section of the Data Source settings seems to be failing to include within requests.

I’ve got some JSON I’d like to see in every request I make, and only fields I’ve updated through the Skuid UI are being put into the body. I feel this might be similar to a post I made about header values not being populated. https://community.skuid.com/skuid/topics/rest-models-put-invalid-json-request-bodies
