It's easier to read the traceback if the linebreaks are left in! You can format as a code block using triple backticks or the "code" button in the editor.

It looks like the code was expecting to find a list of kpoint labels, but internally found a None instead. Was the KPOINTS file generated using sumo-kgen, or something else?
