Key Bindings Puzzle

[Firesong]

https://wowpedia.fandom.com/wiki/API_GetBinding

I've all my keys set to default.

The code sample for me just prints "Movement Keys > Turn Right (TURNRIGHT) is bound to: " So GetBinding is getting nothing.

https://wowpedia.fandom.com/wiki/API_GetBindingByKey

I have "Blade of Justice" on 1.

bindingAction = GetBindingByKey("1")
print(bindingAction) prints nil

Can anyone tell me what I am doing wrong? Is there a WoW settting that is needed for GetBinding or GetBindingByKey to work?
