Find files starting with <string> -- Frustration

Although my current playbook doesn’t look for ifcfg files directly, I am just trying to grab a list of files and it is failing. I can’t, for the life of me, figure out why. If I change the find: to a command: and then run an ls, it works… wondering if someone can put me on the right path. Not making any real progress on my own…

Ultimately I am trying to find files starting with ifcfg- in the specified directory.

Side question: Where can I find a list of debug output types for my vars (ie. stdout, stdout_lines, etc)?

Thanks in advance

Perfect. Thank you. That was the information I needed. I saw the return values earlier in the documentation, but I assumed I didn’t understand it. Thx for the debug info too, that will help me in the future.
