Error When Generating Physical Skeleton

Godot Version

4.1

Question

I created a mesh in Blender, then used Mixamo to generate a skeleton with animations, which works in-game. However, when I click “Generate Physical Skeleton,” I get 11 errors in Output that all say the same thing: “The target vector and up vector can’t be parallel to each other.” What does this mean? This is my first time working with physical bones, and so I am also not sure if the bone positions in the screenshot are correct or wrong.
