Issue Description

Disclaimer: I am very unfamiliar with profiling, for context I am plugging Sentry to a new side project and saw this new feature and decided to enable it.

I just setup vernier for my profiling on a new, simple Rails app. My app runs background jobs (via solid_queue), including cron jobs. Some of the cron jobs (not all of them) return this internal error from Vernier. Weirdly, trying to re-run them from MissionControl, again, sometimes it fails, sometimes it passes.

It is not blocking anything on my side at the moment. I will monitor this to share some numbers, but if you already have some questions or ideas at what I should look at to help, let me know.

Note that this error is not reported by Sentry in the issue tracker.
