error with selector attribute

[nsheff]

I'm not sure why this is not working on microtest:

looper run config/microtest_config.yaml -d --selector-attribute "protocol" --selector-include "ATAC-seq"

TypeError: hasattr(): attribute name must be string

maybe a python3 problem?

My guess is that looper reads the inclusions/exclusions from the CLI as a list (nargs='*'), and then that value is being passed through the ProjectContext and requested as a single attribute on a Samlpe
