## Related Issue

Related to #804 

## Type of change

- [X] Bug fix (non-breaking change which fixes an issue)

## Checklist before merging

- [X] (Optional) Changes have been linted locally with
[golangci-lint](https://github.com/golangci/golangci-lint). (NOTE: We
haven't turned on lint checks in the pipeline yet so linting may be hard
if it shows a lot of lint errors in places that weren't touched by
changes. Thus, linting is optional right now.)
