RESTful Config Issues

I have a restful config that is returning the following error:

Error: [object Response]

I tested outside of AppGyver and I am getting a proper response:

HTTP/1.1 200 OK
Cache-Control: no-cache
Content-Length: 2623
Content-Type: application/json; charset=utf-8
Date: Tue, 7 Mar 2020 09:53:37 GMT
X-Cws-TransactionId: 6c3db4d6-125f-4ea3-b938-882bc5dc3caf

“principal”: “”,
“subject”: “16…”,
“token”: “ey1…”,
“openIdToken”: “ey1…”,
“expiresIn”: 3600

In the AppGyver Data section for the restful call, I have the body and headers params, set as a POST.

I have tried to do a custom POST response as object, but never gets the data. Any help greatly appreciated.

It could be missing CORS headers in the response. Any chance of opening the Web Inspector console via Option + ⌘ + J (on macOS), or Shift + CTRL + J (on Windows/Linux) and pasting a screenshot of the error? Improving the error handling is on the backlog.
