Sorry for the delay getting back to this -- I didn't realize I hadn't enabled notifications on the thread. The GCS docs suggest that 400 errors should be accompanied by an explanation in the reply body. > Error responses usually include a JSON document in the response body, which contains information about the error. https://cloud.google.com/storage/docs/json_api/v1/status-codes Do you think we're not getting an http response body here, or that it's not being printed out?
