I've run against this with Storage and Bigquery too. We should get better at detecting the failure leading to this. Will look at it carefully.

Okay, I've worked out why we're getting an ArgumentNullException instead a more useful exception - when ResumableUpload.UploadAsync catches an exception thrown by InitializeUpload, it reports it but goes ahead anyway. Adding a return Progress; statement fixes that bit, but we don't end up with a nice exception that includes the details of why the request failed. That will take a little more work.
