Description

Team/group_ids are not being added to approval rules as part of our project's mr_approval_rules, we have seen inconsistency in the rules being applied, after running the terraform apply for the same configuration we see group sometimes being added and sometimes not. We have tested with different approval groups such as developer, reporter and maintainer.
