I couldn’t find anywhere to report bugs so I’m going to report it here.
So I was creating a couple of commands that go kind of together. One is for healing people and the other one is for feeding people.
These two commands have the exact same code except one uses HealthData and the other one uses FoodData instead.
The healing command works fine. The feeding one does feed and does it correctly but it gives an error.
As for what the stacktrace tries to say; it seems to be an implementation issue. Implementation may not be finished for what you’re trying to use. You can pop an issue onto the repo to get more attention to it.
