33 events from 7 different (Sentry) users. Although only two are logged in users and those usernames look like the same person might be running two accounts. So it might only be from a single device (a Samsung SM-A205YN).

We're seeing this error:

TypeError: Cannot read property 'uuid' of undefined

...which comes from sw.js:806.

All observations should have a UUID, but in this case it seems there isn't an observation. We need to find out what was written to the DB.
