LSP "response id must be a number" error in neovim (regression?)

[nickjer]

It seems with the introduction of 1.9.0 that issue #1246 has regressed and shown back up again.

Following the steps outlined in neovim/neovim#30638 I managed to capture the problematic event again...

...squashfs-root/usr/share/nvim/runtime/lua/vim/lsp/rpc.lua:442: response id must be a number: {

Let me know if there is anything I can do to help with this.
