BIGIP_USER Ansible with CSV

I've been having an issue with the F5 bigip_user module and the read_csv module together.

I want to feed a list of users to the playbook that calls the bigip_user module and iterate through it to update our BIG-IP's. Everything works great except when shell=bash from the CSV. If I statically set the value to bash, the playbook runs successfully. If I set the shell to none or tmsh in the CSV the playbook finishes successfully. If I change shell=bash in the CSV, that entry fails. I've attached a screenshot of the playbook. I'm running this from CentOS 8. I'd appreciate any suggestions on what I might be missing. Thanks!
