How to pass urlencoded string to jenkins api using ansible?

I have to pass value to jenkins api. But jenkins api accept value in urlencode. I tried to use filter urlencode in ansible, but it gives error.

- name: Add credential to add node
  uri:
      body: |
          json={
              "": "0",
              "credentials": {
                "scope": "GLOBAL",
                "id": "jenkins_linux_slave2_auth",
                "username": "jenkins",
                "password": "",
                "privateKeySource": {
                  "stapler-class": "com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey$DirectEntryPrivateKeySource",
                  "privateKey": '{{"URL ENCODED STRING"|urlencode}}'
                },
                "description": "Jenkins Linux Slave2 Authentication",
                "stapler-class": "com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey"
              }
            }
      force_basic_auth: yes
      method: POST
      password: "{{ jenkins_user_token }}"
      status_code: 302
      url: "{{ jenkins_url }}/credentials/store/system/domain/_/createCredentials"
      user: "{{ jenkins_user }}"
      validate_certs: no
  tags:
      - credential

This play gives error

}

Is there another way to pass value in urlencode in jenkins ?
