Error wmgx: TypeError: 'zip' object is not subscriptable

I am testing the wmgx workflow using demo files and am running into an error. It appears that the error is specific to the script “shotgun.py”

(biobakery_prod) fatimas**@alustt129** PROD$ biobakery_workflows wmgx --input /home/nicoleg/.conda/envs/biobakery_prod/tutorial/input/ --output ~/test-wmgx_prod/Testing_Output_wmgx_demo --local-jobs 2 --bypass-strain-profiling --contaminate-database /home/nicoleg/.conda/envs/biobakery_prod/tutorial/kneaddata_demo_db/

Traceback (most recent call last):

Any input is appreciated. Thank you
