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](http://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:**
