[BUG] tailscale status task output sometimes fails to parse as json

[whysthatso]

Describe the bug
I'm not certain if this is a bug. I'm running the role like this:

    - name: include tailscale role
      ansible.builtin.include_role:
        name: git.artis3n.tailscale

and I'm getting this error:

TASK [git.artis3n.tailscale : Install | Parse status JSON] ******************************************************************************************************************************************************
fatal: [docker-host-1]: FAILED! => {}                                                                                                                                                                            
                                                                                                                                                                                                                 
MSG:                                                                                                                                                                                                             
                                                                                                                                                                                                                 
The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'Self'. 'dict object' has no attribute 'Self'                                                              
                                                                                                                                                                                                                 
The error appears to be in '/home/user/ansible/roles/git.artis3n.tailscale/tasks/install.yml': line 67, column 3, but may                                                                    
be elsewhere in the file depending on the exact syntax problem.                                                                                                                                                  

The offending line appears to be:


- name: Install | Parse status JSON
  ^ here

Everything is dandy when i run it traditionally:

  roles:
    - git.artis3n.tailscale

Is this related on how facts get set, and that include_role works differently here?

[artis3n]

Hmm, I do have multiple integration tests using include_role, check out molecule/args/converge.yml and molecule/state-idempotent/converge.yml, for example. I suspect there's a variable issue at play.

Do you have a variable overriding status? Because the error seems to be that the variable isn't formatted correctly.

ansible-role-tailscale/tasks/install.yml

Line 69 in 48a5ccc

status: "{{ tailscale_status.stdout | from_json }}"

I should really modify that to a role-specific name anyway, that's too generic of a name... but let me know if you can isolate the issue into a reproducible minimal playbook.

I actually have experienced the same issue. Let me know if/how I could help with troubleshooting/resolving this.

This is how it is invoked here:

- name: Install tools
  hosts:
    - qix_oob
  become: yes
  strategy: free
  vars_prompt:
    - name: tailscale_authkey 
      prompt: Tailscale authkey?
      private: true
  tasks:
    - name: Install a list of packages
      ansible.builtin.apt:
        pkg:
        - tcpdump
        - iperf3
        - netcat
  roles:
    - role: artis3n.tailscale

When ran the second time, the error message is gone.

This should be fixed by #431 , I'll publish a new release soon
