Ansible - Replace " and \r\ in a variable - replace

Question

I want to replace the " and \r\ from a variable content using Ansible.
I have the following data in a variable result thatI register the output to the variable from the previous task
curl -s -H \"Authorization: JWT eyJ4NWMiOlsiTUlJQytqQ0NBHuHO96csEQ\r\" https://hub.docker.com/v2/repositories/talasecurityinc/?page_size=10000 | jq -r '.results|.[]|.name'
In the above content I want to replace the \ and \r\ with null.
I have tried the below way but it doesn't work for me.
- set_fact: final_out="{{result | replace('\', "") | replace('\r\', '')}}"
The expected output is
curl -s -H "Authorization: JWT eyJ4NWMiOlsiTUlJQytqQ0NBHuHO96csEQ" https://hub.docker.com/v2/repositories/talasecurityinc/?page_size=10000 | jq -r '.results|.[]|.name'
The example playbook snippet would be helpful for me since I am new to ansible.

Escaping Hell....
I was not able to use replace, probably because I didn't try hard/smart enough. Meanwhile, in your specific case, you can achieve the expected result with a single regex_replace filter call so it was easier (and it worked right away :)).
I used yaml folded blocks (>) with white space control (-) to minimize the escape hassle. If you don't know what that is, have a look at a yaml doc (learn yaml in y minutes is my favorite one)
Note that the remaining backslashes in the last result below are added by ansible to escape the double quotes in the output.

- name: Escape chars
hosts: localhost
gather_facts: false
vars:
test: >-
curl -s -H \"Authorization: JWT eyJ4NWMiOlsiTUlJQytqQ0NBHuHO96csEQ\r\"
https://hub.docker.com/v2/repositories/talasecurityinc/?page_size=10000
| jq -r '.results|.[]|.name'
tasks:
- name: Show the untouched var
debug:
var: test
- name: Escape the var as intended
debug:
msg: >-
{{ test | regex_replace('\\r?\\?', '') }}
which results in
