Hey,

Thanks for the report. I can confirm this; it seems like Go has started panicking here where it didn't before. Let me see if I can come up with a solution that fixes this without waiting for a Go patch here. In the mean time, you can use Go 1.18 to compile.

I've got a patch in #108 which should address this. It bumps the required version of Go from 1.11 to 1.16, which I think should be fine here, and I've verified that the server starts correctly in that case and the management endpoints can be accessed correctly.
