Can't send JSON code using uri module

[Sharwari Phadnis]

I am trying to send a JSON payload using uri module through body parameter. The variables {{ network-name }} and and {{ IP1 }} are imported from config.yml.

I have defined body in vars. The json code which I am trying to print is getting created properly using (debug: var={{ body | to_json}}). But, the output which I am redirecting to the dest file is showing errors. What could be the reason that the JSON payload is not getting sent at the destination url.

Here's the ansible playbook:

---
- hosts: localhost
  connection: local
  vars_files:
    - config.yml
  vars:
    body:
      id: 100
      network:
        name: "{{ network-name }}"
        net_list:
          - link_id: 1
          - type: abc
      vlan: "10"
      profile: switch

  tasks:
    - debug: var="{{ body | to_json }}"
    - name: Run POST command
      uri:
        url: "https://{{ IP1 }}/url/to/dest"
        method: POST
        body: "{{ body | to_json }}"
        user: "abc"
        password: "xyz"
        HEADER_Content-Type: "application/json"
        force_basic_auth: yes
        return_content: yes
        dest: /url/to/dest/file
