TypeError: sum() takes no keyword arguments

Hi Lukas,
I created a boundary vertex groups (with a selection of boundary vertices) and hit 'Geodesic distance'
and get the following error.

No Complains or bug fixing request here, just curios and wanted to play around.
Is this on my side?

This is a problem with the python 3.7.7 version in Blender 2.92. I'm targeting 2.93, which uses python 3.9, so i recommend using the beta for testing.

I have removed the offending keyword and it should now work in Blender 2.92 again. Thanks for reporting.
