Ansible copy ssh public key from file, use in uri call - regex

Question

I need to copy the SSH public key from a local file, then use it in a uri task in my playbook.
Keep in mind, I cannot use "authorized_key" module as this is a system I must use the API to configure public keys for users.
Code below keeps failing, I am 100% sure its because of the filter I am using. I am including the commented out section that does work for the body.
Trying to use a lookup with a regex_search, I used [^\s]\s[^\s] which works in python. Also the key is in a different directory in my local host (../../ssh/ssh_key/key.pub)
Any ideas?
- name: copy public key to gitea
hosts: localhost
tasks:
- name: include user to add as variable
include_vars:
file: users.yaml
name: users
- name: Gather users key contents and create variable
# shell: "cat ../keys/ssh_keys/zz123z.pub | awk '{print $1 FS $2}'"
shell: "cat ../keys/ssh_keys/{{item.username}}.pub | awk '{print $1 FS $2}'"
register: key
with_items:
- "{{users.user}}"
- name: Add user's key to gitea
uri:
url: https://10.10.10.10/api/v1/admin/users/{{ item.username }}/keys
headers:
Authorization: "token {{ users.GiteaApiToken }}"
validate_certs: no
return_content: yes
status_code: 201
method: POST
body: "{\"key\": \"{{ key.stdout }}\", \"read_only\": true, \"title\": \"{{ item.username }} shared
body_format: json
with_items:
- "{{users.user}}"
This is the error I receive when using -vvv

I FIGURED IT OUT!
used shell with an awk command to gather the keys. (Note: including an awk for RSA keys, and one for id_ed25519, which we use. RSA is commented out but others can comment if they wish to use.)
Used loop control to iterate through the results.
Code below:
- name: copy public key to gitea
hosts: localhost
tasks:
- name: include user to add as variable
include_vars:
file: users.yaml
name: users
- name: Gather users key contents and create variable
# For RSA Keys
# shell: "cat ../keys/ssh_keys/{{item.username}}.pub | awk '/-END PUBLIC KEY-/ { p = 0 }; p; /-BEGIN PUBLIC KEY-/ { p = 1 }'
# For id_ed5519 Keys
shell: "cat ../keys/ssh_keys/{{item.username}}.pub | awk '{print $1 FS $2}'"
register: key
with_items:
- "{{users.user}}"
- name: Add user's key to gitea
uri:
url: https://10.10.10.10/api/v1/admin/users/{{ item.username }}/keys

validate_certs: no
return_content: yes
