Error while trying to add "TypeError: '<' not supported between instances of 'NoneType' and 'int'"

Hi,

I was running the command line to add hits into my blobtoolkit file (command just below) when I receive a python error.
Could you help me identify the error?
I installed the blobtoolkit with conda.

blobtools add --hits blastn.out
--hits diamond.blastx.out
--taxrule bestsumorder
--taxdump ./taxdump/ ./btk

Loading parsed taxdump
