AnsibleUndefined in Tower execution

[Aharonu]

Hi Everyone,

I have playbook executed in Ansible server and it is successful but when i execute the same in Tower I am getting  1. AnsibleUndefined, 2. Dict converting to string.

I would like to understand what makes a difference and a solution for it. Thank you.

Under vars i have defined -

vars:
    failed_list: []
  failed_lists: "{{ dict(groups.all| zip(hostvars|dict2items| map(attribute='value.failed_list', default=[]))) }}"
  failed_hosts: "{{ failed_lists|dict2items| selectattr('value')| map(attribute='key')|list }}"

Under 'rescue' section -

rescue:
   - set_fact: failed_list: "{{ failed_list + [ansible_failed_task.name] }}"

Below output for:

- name: failed_lists | groups all | hostvars|dict2items | attribute='value.failed_list' | dict
  debug:
    msg: "{{ dict(groups.all | zip(hostvars| dict2items | map(attribute='value.failed_list', default=[]))) }}"

Result in server: 

TASK [failed_lists | groups all | hostvars|dict2items | attribute='value.failed_list' | dict] ***********************************************************************************************************************************************
ok: [TestCluster1] => {}

MSG:
