[erlang-questions] possible dialyzer bug

[Zachary Kessin]

I have a strange dialyzer problem, I have this code

                  case convert_map_to_record(MapId, UserId, ClientId,
Terms) of
                      {ok, MapRecord} ->
                          %....
                          {true, ReqData1, MapRecord};
                      {error, Error} ->
                          lager:error("Error ~p", [Error]),
                          {{error, 405}, ReqData, State}
                  end

and dialyzer is saying this

_build/default/lib/frontend/src/wm_map.erl
 100: The pattern {'ok', MapRecord} can never match the type {'error',_}

With what is line 100 being the line with the red background, what is
strange is that that the error case is covered in the case statement
