Error: "reason": "no action detected in task

Hi there, During erpnext installation using easy install script, I am getting “no action detected in task” as shown in the screenshot below.

When I investigate line 14 of the said file below /tmp/.bench/playbooks/roles/mariadb/tasks/mysql_secure_installation.yml
I dont see anything that could be causing the error.

Any one who has an idea why this is so?
