State changed event for a schedule input helper

I have a schedule input helper that I am trying to trigger a flow from in Node Red using the state changed event. I am able to create an automation in Home Assistant with a state trigger that has that input helper as the entity. In addition, the entity shows up in Node Red in the current state node so I know that Node Red knows about the input helper. However I cannot get it to show up to select in the state changed event nor the trigger state node.

Other types of input helpers work with no problem.

Any advice would be appreciated.
