ansible-runner: stdout and stderr files are empty after the run.

[siva-vaddipati]

Hi,

I am running the ansible playbooks using ansible-runner in a container.
I'm using the below command to run the playbook,

`ansible_runner.run_command(
        executable_cmd='ansible-playbook',
        cmdline_args=['/pbs/playbook.yaml', '--tags', task, '--extra-vars', extra_vars, '-vvvv']
        status_handler=ansible_status_handler,
        envvars=envvars,
        runner_mode='subprocess',
        artifact_dir='/artifacts',
        ident=ident,
        timeout=timeout,
        output_fd=sys.stdout,
        error_fd=sys.stderr,
    )`

In my playbook I am also referring to my ansible.cfg, which has
#stdout_callback = awx_display commented out. I have also tested by uncommenting this line but the result remains the same.

once the play starts running, I am also seeing the below logs on the pod,

`Skipping callback 'awx_display', as we already have a stdout callback.
Skipping callback 'default', as we already have a stdout callback.
Skipping callback 'minimal', as we already have a stdout callback.
Skipping callback 'oneline', as we already have a stdout callback.
`

Once the run completes, I observed that the stdout and stderr files in /artifcats/{runner_id} are created but they do not have any content. However, the job_events directory has *-partial.json files. I am able to see the all the ansible logs on the terminal of the pod, but the stdout file is just empty after the run.
Please let me know if I need to configure anything else.

Thanks in advance.
