GroupWikiRepositoryReplicator - Repository cannot be checksummed because it does not exist

Summary

Geo Group Wiki sync added in 16.3 fails if a Group is missing a wiki repository.

ZD 451059 (Internal) for detailed customer logs.

Steps to reproduce

Unknown, I'm unsure how the customers server ended up with a group that's missing this repository.

Example Project

n/a

What is the current bug behavior?

During a Geo sync the group wiki verification fails leaving a red bar on the Geo summary screen.

What is the expected correct behavior?

Unsure, does something like the auto create that was added to the Project Wiki needed adding here? !123869 (merged)

Workaround

Run the following in the Rails console on the primary site:

::GroupWikiRepository.verification_failed.each_batch do |wiki_repositories|
  wiki_repositories.each { |wiki_repository| wiki_repository.group.create_wiki }
end
