Is there a way to check to see if a slot is filled? I am trying to conditionally re-run an action if it is not filled.

Thanks! I figured it out! I realized I could simply attempt to get the slot value and check `if VALUE is None:`.

If you are reading this and you are new to python as I was, here is what I did: Check for the string ‘None’ if your default slot value is None. I was busy checking None, the primitive type.

So, you can do something like:

`if id == "None":`
