I think this might be relevant,

We noticed a few errors in our discourse logs related to docker manager when our discourse went White Screen after upgrade.

```plaintext
NoMethodError (undefined method `find_compatible_git_resource' for Discourse:Module)
/var/www/discourse/plugins/docker_manager/lib/docker_manager/git_repo.rb:116:in `tracking_branch'

```
