Replacing the baseUrl with https://services.odata.org/V4/(S(oygeljzs0rz0wq0k2vd4j3zk))/TripPinServiceRW/, so this seems to be a communication problem between GraphQL Mesh and the Jetsons service.

Appears to be due to the fact that Mesh is not sending application/xml in the accept header for metadata, so if the service defaults to application/json they are not able to handle the response since they only support xml.
