What went wrong?

What happened:

I updated to OnCall 1.10.1, and then this happened:

I... honestly have no idea what the error is. I mean, sure, there is an error, but I have no idea what or which one.

What did you expect to happen:

A working OnCall...

How do we reproduce it?

1. Update from 1.9.20 -> 1.10.1
2. Run migrations
3. Start the updated instance.
4. Grafana will likely want to have it's plugin updated and reconfigured too - so do that.
5. Upon clicking "Connect", observe this error in the logs.
