Hi, 

We are integrating a hybrid app with the REST API but are getting random errors from SalesForce. I have logged 2 instances of the app running in which a call is correctly handled and another where an error is returned by the REST API. The thing is... the 2 calls seem to be identical aside from an AccessToken that has been refreshed already and a single attribute (lastModified date) in the query.

The REST API complains that the Entity Body is empty when in fact I think that is always empty in a GET call. Can anyone help me out? This is realy driving me bonkers because it seems to go wrong at random intervals

CALLS: (OAUTH token removed)

Call correctly handled:
