WPA4 invalid JSON response with a valid session

Install the agent with JSON-response properties set. Make sure json-response URL value is not part of the not-enforced url list (direct value or by any wildcard pattern). Get some other (agent protected) resource authenticated and extract the session cookie value. Do the request to json-url with a session cookie set.

Expected: agent does not interfere with the requested resource and does not change json reponse.

Actual: agent responds with this json response:

{"error": { "errors": [

{ "message": "success", "data": "" }

], "code": 0 }}
