I also encountered this on my Guix configuration (on a foreign 
distro). I tried to investigate into it, but I got confused.

The error message I got is:
> slot-missing: Invalid slot name: "#<eglot-lsp-server 
> eglot-lsp-server-170231c>", :events-buffer-config

However, events-buffer-config (it is defined in 
jsonrpc-connection, and eglot-lsp-server inherits that if I read 
correctly) is introduced in jsonrpc.el at 
e0b9944b69ff72923c29756fcfcea9528a3f5069, which is included in 
1.0.23.
