A media upload to rupload.facebook.com failed. That host is not Instagram's
API — its answers never reach the session-header parser and are never mapped to
the API's typed errors — so the upload reports its own failure, in one of two
shapes that share the tag MessengerMediaUploadError (one catchTag handles
both) and are told apart by reason.
