Zone Level Humidification Control

I am modeling a multizone AHU with zone level reheat and humidification in Openstudio. I tried using the OS:Humidifier:Steam:Gas object placed between the air terminal and the thermal zone, but I get an error stating that the selected component is not allowed at the node between the zone and the humidifier when I try to place a minimum humidity setpoint manager. The simulation fails if I try to run without a setpoint manager, which is expected because the Eplus input output reference states "A humidity set point manager is needed to put a setpoint on the outlet node..". Its Strange that OS allows me to put a humidifier object on the zone branch but not a set point manager. Looking further into the input output reference for this object, I don't see any limitations on the placement of the humidifier. Are there any workaround for this issue? Is there something I'm missing? See image below for image of the configuration and the issue.
