Hi,

after upgrading to emacs 29.3 eglot fails to start with an error message like

Invalid slot name: "#<eglot-lsp-server eglot-lsp-server-cacbec>", :events-buffer-config

This also happens if I start emacs with 'emacs -q' and activate just eglot manually.

I'm using not the build-in eglot package, but emacs-eglot@1.17.  This package has a dependency to emacs-jsonrpc@1.0.23

Upgrading jsonrpc to version 1.0.25 solved the issue for me.

Yours,

Lilly
