wrong kind of value returned from append_to_stream

[norpan]

I get the following error. It seems that append_to_stream returns an error triple, but only error tuples are allowed.

** (WithClauseError) no with clause matching: {:error, :CommitTimeout, %Extreme.Msg.WriteEventsCompleted{commit_position: 0, first_event_number: -2147483648, last_event_number: -2147483648, message: "Commit phase timeout.", prepare_position: -2147483648, result: :CommitTimeout}}

I've got the same issue here, no sure how it should be solved
