Had another user with similar issues on the 4xx errors. They have suggested that it would be good if the upload methods returned details of the operation instead of being void.

e.g.: filename, status code, is error, error reason

Not sure that fits with our model of throwing an exception instead, we should probably discuss and agree the right way forward
