Adding custom iterator to Godot not working

[MyStarrySpace]

Hi there,

I am setting up the Godot ECS for the first time, and it seems to not be working. When I run the code, I get the following:

After trying to build Godot, I then get the following:

Can confirm on Linux as well - following the Setup page, a similar KeyError happens after applying the patch.
