Short timestep for ventilation control

Hello @chris,
I faced a problem while dictating a ventilation in a short period (timestep 60) for window opening. I have experience in getting the demanded results with Ladybug 1.0.0 version, but I need to use thermal comfort mapping tools which is developed in Ladybug 1.2.0. Now I face an error as in the picture. would you mind help me in this case?
Error: 1. Solution exception:Expected argument 1 of type std::string const &, but got Integer 1
