I’m running into trouble to find the answer that how to negate the conditional with regex. Something like below:

- debug: msg=“{{ Hello World}}”  
when:- test.rc !=0

- test.stderr | find (‘(No Such File or Directory)’)

- debug: msg=“{{ Hello Friend}}”  
when:

- test.rc !=0

- \<would like to use negate of “test.stderr | find (‘(No Such File or Directory)’)”\>

Looking for the expert help on this !

Thanks

- rest.rc != 0
- ‘No Such File or Directory’ not in test.stderr
