Im thinking…, why this does not work?

**Task:**

- name: Run validation query on db localy  
shell: docker exec -i postgres bash -c ‘psql -v --username “postgres” --dbname “postgres” -c “select 1”’  
delegate\_to: “{{ item }}”  
with\_items: “{{ groups.postgres\_server}}”  
register: validation  
until: validation.results[0].stderr == “”  
retries: 10  
delay: 30  
ignore\_errors: false  
become: true  
become\_user: root  
become\_method: sudo

**Result:**  
fatal: [localhost]: FAILED! =\> {“failed”: true, “msg”: “The conditional check ‘validation.results[0].stderr == ""’ failed. The error was: error while evaluating conditional (validation.results[0].stderr == ""): ‘dict object’ has no attribute ‘results’”}

**Task:**

- debug:  
msg: “{{ validation.results[0].stdout }}”

**Result:**  
ok: [localhost] =\> {  
“msg”: “”  
}

I guess that i have compare it like…

- debug:  
msg: “{{ hostvars[inventory\_hostname][validation.results[0].stderr] }}”

But still not working…
