Run biobakery_workflows wmgx example failed, maybe some problems in

First, this is the error message:

2022-05-30 17:40:46,756 LoggerReporter task_failed ERROR: task 35, strainphlan_print_clades : Failed! Error message : Error executing action 0. Original Exception:

And I tried to change all the codes in …


because I thought it should be the same as

but still got the same error ~

And I’m guessing that maybe the problem is right here…

Are you free to help me out? Thanks a lot !
