Ansible iterate over array and use filter - ansible

Question

I'm kinda new to ansible seeking help with below scenario. what I'm trying to do is iterate over the array 'access_key_ids' and run regex_search filter. for the regex_search filter argument is 'item' which is the variable from with_items. It does not work this way below is what I'm trying.
name: Set Fatcs
block:
# extract access key ids from get event response
- set_fact:
event_response_access_key_ids: "{{event_response_access_key_ids}} + [{{event_response.content | regex_search(item)}}]"
with_items: "{{access_key_ids}}"
# check if the response contains access key id for the license
- set_fact:
scwx_output: "{{ (event_response_access_key_ids | length > 0 ) | ternary(event_response, 'License Key does not match with available sensors')}}"
when: event_response.json is undefined
It gives event_response_access_key_ids as empty. but when I hard code a value instead of 'item' it works
Thanks.

I've been testing this solution:
---
- name: Test
hosts: local
gather_facts: False
vars:
event_response:
content: "hi1"
access_key_ids:
- "1"
- "h"
- "3"
tasks:
- name: Fact
set_fact:
event_response_access_key_ids: "{{ event_response_access_key_ids|default([]) + [ event_response.content | regex_search( item ) ] }}"
with_items: "{{ access_key_ids }}"
And It gets the vars properly:
ok: [localhost] => (item=1) => {
"ansible_facts": {
"event_response_access_key_ids": [
"1"
]
},
"changed": false,
"item": "1"
}
ok: [localhost] => (item=h) => {
"ansible_facts": {
"event_response_access_key_ids": [
"1",
"h"
]
},
"changed": false,
"item": "h"
}
ok: [localhost] => (item=3) => {
"ansible_facts": {
"event_response_access_key_ids": [
"1",
"h",
null
]
},
"changed": false,
"item": "3"
}
