Issue with Git submodules #442
Description
I've recently got the idea to consolidate Allstar configurations as git submodules. That way configurations can be centralized in several repositories and I can more easily switch between configurations for different collections of repositories.
However, I found that submodules make Allstar crash with the following error logs:

Any idea how this runtime error could be fixed?
