ignore -has no attribute

Hello Team,

I am parsing register value using debug and using when condition to print particular matching value. While doing that am getting below error. some of the register value doesn’t have “volume_attachments” variable due to that the when condition is failing. I want to ignore this error how can I do it. Could you please help me on this. Thanks in advance.

fatal: [localhost]: FAILED! => {“msg”: “The conditional check ‘item.volume_attachments | length == 0’ failed. The error was: error while evaluating conditional (item.volume_attachments | length == 0): ‘dict object’ has no attribute ‘volume_attachments’\n\nThe error appears to be in ‘/var/lib/home/s’: line 33, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - debug:\n ^ here\n”}

Regards,
Jegan A

Use "default" filter:
https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#defaulting-undefined-variables

Example:
- hosts: localhost
  gather_facts: no
  vars:
    d:
      key: value
  tasks:
    - debug:
        msg: "{{ d.missing_attr | default('default_value') }}"
