Ansible extract values from stdout_lines to use in subsequent loop - ansible

Question

I am trying to write a role to remove all helper addresses for a Cisco Router interface. There can be one or more helper addresses returned in stdout_lines. I use filters to remove labels and extra scapes from the lines and put the results into an array to use in the subsequent command loop. I seem to get the correct info but using the value fails.
Here is my role:
---
- name: read helpers
register: helper_facts
ios_command:
commands:
- show ip interface {{ interface }} | section Helper
- set_fact:
helper_addr: []
- set_fact:
helper_addr: "{{ helper_addr }} + [ '{{ item | regex_replace ('Helper address.* ','') | trim }}' ]"
with_items: "{{ helper_facts.stdout_lines }}"
- name: remove helpers
ios_command:
commands:
- no ip helper-address {{ item }}
with_items: "{{ helper_addr }}"
Here is a snip of the output with the error I get:
ok: [ONTMDFRTR01] => (item= 172.16.0.22) => {
"ansible_facts": {
"helper_addr": [
"192.1.0.1",
"172.16.0.22"
]
},
"ansible_loop_var": "item",
"changed": false,
"item": " 172.16.0.22"
}

Answer 1

Thanks to mdaniel's comment I found the answer. I cut this from a larger playbook and left out the commands to setup the interface ("config t" , "int GigabitEthernet0/0/0") needed before the no helper_addres command. My role is now working as expected. Thanks, I hope this helps someone else.
