Mingle - An Introductions Plugin

Has anyone experienced a 502 bad gateway error after installing the plugin?

I validated the YAML file, rebuilt as the instructions mention, and then couldn’t access the site. After reverting the changes to the YAML file and rebuilding again, everything was fine again.

This is what I added to the YAML file, for reference:

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git
          - sudo -E -u discourse git clone https://github.com/gdpelican/mingle.git
