Lot's of weird and wonderful sentry errors

[DavidM-D]

We set up alerts for uncaught errors on the fastauth frontend using sentry.

There are a decent number of these and we have no idea whether they're benign or the result of something failing in a nasty way.

These errors can be found on our slack channel #emerging-technologies-alerts pick one and get to the bottom of it. Report the one you picked and your progress here.
