Error Lookup Private Key in Post Request

Archives Ansible Developer

I have an error in the post with the uri module.
I need to create a credential for my Vagrant VM on Jenkins via api.
In my tests, I realized that the error is in passing the value of the private key, in this line:

privateKey": “{{ lookup(‘file’, ‘…/.vagrant/machines/protheus/virtualbox/private_key’)}}”

If I pass the value of the private key manually, in just one line the credential is created without errors.

My task:

  • name: Get Private Key Value
    debug: msg=“Private Key Value is {{ lookup(‘file’, ‘…/.vagrant/machines/protheus/virtualbox/private_key’)}}”

  • name: Get Jenkins Crumb
    uri:
    url: “{{ master_url }}/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)”
    user: “{{ master_username }}”
    password: “{{ master_password }}”
    force_basic_auth: yes
    return_content: yes
    register: crumb

  • name: Create a Jenkins Credential

Does anyone know what could be wrong with my task?
