Reviewer roulette

Changes that require review have been detected! A merge request is normally reviewed by both a reviewer and a maintainer in its primary category and by a maintainer in all other categories.

To spread load more evenly across eligible reviewers, Danger has picked a candidate for each review slot. Feel free to override these selections if you think someone else would be better-suited or use the GitLab Review Workload Dashboard to find other available reviewers.

To read more on how to use the reviewer roulette, please take a look at the Engineering workflow and code review guidelines. Please consider assigning a reviewer or maintainer who is a domain expert in the area of the merge request.

Once you've decided who will review this merge request, mention them as you normally would! Danger does not automatically notify them for you.

requested review from @GitLabDuo

I have left a recommendation regarding a misplaced closing brace that would cause a compilation error. In my review, I focused on syntax and code structure. I estimate there is a small amount of work required to address this issue, though this is only an estimate based on the single comment provided.
