"AttributeError: 'NoneType' object has no attribute 'attrib'" when using "res_band" in custom footprint

[dhaillant]

I'm creating a set of custom footprints for PcbDraw. And lately, I tried to add the res_band feature for the axial resistors, with no luck.

Once I add a rectangle named res_band1, pcbdraw crashes with this message:

The rectangle is copied/pasted from one of the resistors in pcbdraw-lib.

Inkscape is V1.2 (1:1.2.1+202207142221+cd75a1ee6d)

Is there any setting, configuration that must be applied to the svg for the res_band feature to be recognized?

Thanks!

BTW, this is with populate command.

Did you add the other res_bands (from 1 to 4)? This could be because it is crashing when it is trying to find the other bands after it finds the first one

[dhaillant]

Indeed, it looks like in my first attempt, somehow the script couldn't find one or more of the 3 next bands.

So I copy/pasted the 4 bands at once from a resistor in the official lib to my custom lib and now it works. As @Electro707 suggested, if I remove just one of the 3 bands (not the #1), it rises this error.

I think I understand what happened: In my first attempt, I copy/pasted only one band and renamed it. This was clearly not the right method.

Thanks!
