## Bug description

I set up a self-hosted instance via AWS cloudformation and updated it recently.

The page /instance/status fails to load for me.

## Expected behavior

Instance status page loads successfully.

## How to reproduce

- Set up a cloudformation instance
- ???
- Visit /instance/status
- See report on 500 error from backend

## Environment

- 1.15.1 (latest docker container)

## Additional context

Not able to provide a lot of useful context here due to https://github.com/PostHog/deployment/issues/32
