Strangely, despite enabling both stack-trace-on-error and debug-on-error in the minimal init.el, I do not get a nice backtrace or debugger session when I get the error with the minimal init.el, so I've included (above) what I get with the minimal init.el but I'm also going to include (below) the details I get when loading my full emacs config, because it provides more info and the backtrace and debugger actually work. If you have any ideas how to get the debugger/backtrace to work in the minimal init.el I'd be very happy to hear them, as I honestly can't figure out why they aren't working, and I'd prefer to submit a less janky bug report.

Full backtrace from full emacs config:

emacs start command:

/usr/local/bin/emacs --init-directory=~/Developer/Lisp/ test.rb
The ~/Developer/Lisp/ dir is where my minimal init.el is located.

Reproduction steps:

1. install ruby and the ruby-lsp gem
2. ensure that both ruby and ruby-lsp are in your PATH env var, you can check this with command -v ruby-lsp && command -v ruby
3. create a ruby file, with .rb extension, you can use the contents I provided in test.rb if you like
4. create an init.el file with the contents I provided
5. start emacs in such a way that it uses the init.el I provided and opens the ruby file, you can use the emacs start command I provided to do this if you like
6. the error will show up on its own, might take a second or two on some systems

more info:

• emacs version: GNU Emacs 29.4 (build 1, x86_64-apple-darwin23.4.0) of 2024-06-22
• eglot-version: 1.17 for full-config emacs, builtin: 1.12.29 for minimal-init, both exhibit the same bug
• ruby version: ruby 3.2.5 (2024-07-26 revision 31d0f1a2e7) +YJIT [x86_64-darwin23]
• ruby-lsp version: 0.17.14

Can you start your LSP session with M-x eglot using that init.el?

ah yup that triggered the backtrace, cool.

looks pretty similar to the full-config's bt.

The init.el you supplied has spurious single quotes inside the initializationOptions. That's a mistake. Even without them it's a mistake. Remove the initializationOptions section entirely and try again. Then try without those single quotes and using arrays instead.

[joaotavora]

See https://joaotavora.github.io/eglot/#JSONRPC-objects-in-Elisp-1 for how arrays work

ooooh, well I have to admit i didn't even know elisp had arrays, since it has lists and they're good enough for everything else I've ever done. I'll read that, and yes switching to arrays has fixed the error.
