That is correct. No input is free, they do no free stuff.

But should minecraft crash if you leave all spots empty?

I can understand that nothing happens when you click "teach", or that there is an error message in chat saying "Please select the ingredients!" or something like that. But I would not expect minecraft to crash. That is why I sent them to github

Ahh, this is not a custom recipe, this is attempting to teach a normal recipe? (Custom recipes are datapack recipes with minecolonies support)

This is an architect's cutter recipe, which uses the "custom recipes" tab iirc
