*** Assertion failure in -[GTMHTTPUploadFetcher connectionDidFinishLoading:], /Volumes/data/Work/test/DLNew/DL/google-api-objectivec-client-read-only/Source/HTTPFetcher/GTMHTTPUploadFetcher.m:399

i check the code of GTMHTTPUploadFetcher class it is crashing the app on this link

`#if DEBUG

  NSAssert([[self downloadedData] length] == 0,
                    @"unexpected response data (uploading to the wrong URL?)");
