Ansible: json filtering - json

Question

ill have a role playbook which get json from gitlab
---
- name: Make an API call
uri:
method: GET
url: "https://gitlab.example.com/api/v4/projects/***/repository/files/Dev/raw?ref=master"
headers:
PRIVATE-TOKEN: **************
register: json_var
- name: show json
debug:
msg: "{{json_var}}"
- name: test
debug:
var: json_var.json.plannedrelease
register: release
- name: debug
debug:
msg: "{{ release }}"
but cant get json value to variable, i need only version "1.0" in variable release (from "plannedrelease" : "1.0"), how can i filter it?
Playbook output is:

}
}

probably i used wrong method for filtering

Have you tried https://docs.ansible.com/ansible/latest/collections/ansible/builtin/set_fact_module.html ? Reading the documentation the following might work:
- name: Save release var
set_fact:
release: "{{ json_var.json.plannedrelease }}"
