Ansible unable fail a task based on string search on stdout_lines list

Question

Team,

My below task is supposed to failed based on string in output but its not. what am i missing? Validate all nodes have labels should fail.


      - name: "list node labels"
        debug:
          var: nodeType_label_info.stdout_lines

      - name: "Validate all nodes have labels"
        debug:
          var: nodeType_label_info.stdout_lines
        failed_when: '"does not have" in {{ item }}'
        with_items: nodeType_label_info.stdout_lines
        #failed_when: nodeType_label_info.stdout_lines is not search('does not have')

Fixed it myself. I don't need to store value in var but simply check in failed_when as below

      - name: "Validate all nodes have labels"
        debug:
          msg: "label not found on all nodes"
        failed_when: '"does not have" in nodeType_label_info.stdout'
