Updated playbook

“test\_out”: {  
“changed”: false,  
“failed”: false,  
“msg”: “hello”  
}

there is no key named test here. You need to use ‘test\_out.msg’ above.

Yes that worked, but for the client I am working with, I am unable to change the validation. How would I define it so that test\_out.test would work?

You can't since debug doesn't return test.
