Ok looks like they changed that parameter struct - what you need to do there is disconnect the parameter name and instead do a “break parameter info” node off the parameter info pin, and I’ll bet there’s a name property in that (probably won’t get to a computer this weekend to check). Connect that name property to the == node and you’re good to go.
An update to this for 4.19 is unlikely as I have zero time at the moment. But I do plan to update for 4.20.
