Error validating test apps: 'version'

I'm trying to get contentctl to download apps from splunkbase, but there is no documentation as to how to do that, so I have to keep guessing, but I'm running out of ideas.

Here is my command: contentctl test --verbose mode:all

Here is my contentctl.yml:

splunk_api_username: someone@someone.com
splunk_api_password: hihi
version: 20240925.16.111

app:

container_settings:
  leave_running: true
  num_containers: 1
  full_image_path: registry.hub.docker.com/splunk/splunk:latest

I get this error:

Error validating 'contentctl.yml':
Error validating test apps: 'version'

It doesn't matter if I remove the version key from the contentctl.yml file, the error is the same.

Is this a bug or I'm doing something wrong?

splunk / contentctl
