Weight Manager Auto Weight Not Working

Hello,
I was using the Weight Manager’s Auto Weight feature with point selection selection successfully today. I think I may have accidentally changed a setting, because now I cannot get it to work. My process is:

1. Add my joints to my Weight Tag to my model
2. Add my Skin Deformer as a child to my model
3. If I only want it on a section of the model, I will select points and check “Selected Points” under Basic Parameters
4. Click Auto-Weight’s “Calculate” button

This does match up with the instruction in the Help documentation. These are my settings: https://imgur.com/a/LnOndIh

Nothing happens anymore. No weights are added even though the joints are inside of the geometry and I try different Modes (Heatmap, Distance, and Volumetric). Perhaps it is my workflow, but if it is my parameters, the Weight Manager does not have the “Reset to Default” option.

I have attached a scene file.

Could you please tell me what has gone wrong? Thank you.

Hello, I thought I had tried everything but I have found a solution. My issue was the Basic Parameter “Allow Null Length” was unchecked. I had bones at the end of joint chains that had no bone length because they had no child bones. With the “Allow Null Length” parameter checked, Auto Weight worked as expected again. Thanks for reading!
