I had gotten a character animation done in Blender. I tried to export the GLTF file but I keep getting the Python Error message.

script:

Python: Traceback (most recent call last):

It seems blender does have some problems writing to /var/folders/q8/hd0c9qrj6sd2r9wctjtfmp6w0000gn/T/tmpixx2cddd/img

also using some weird filename : PSD Man - Jacket_Jacket_BaseColor..png.001 ← adding 001 after the extension ??

Also is telling you directly before this:

so it seem the UDIM patter 1001 (or the other variant) isn’t used ??

Additionally i do not know wether GLTF can use UDIM…

nope.
