Volar (containerised) crashes shortly after startup

[WhyNotHugo]

Description

Volar crashes shortly after startup. I can't quite figure out why, nor have any clue on how to debug this further.

I'm running it containerised. I've logged all communication with the LSP by slipping in a special wrapper (note: I only used the wrapper for this bit; all other gathering of logs was done using the LSP normally without this wrapper):

Nvim-lspconfig version

27d2c116fdea5614f422dcbcae63da01a1415fcf

Operating system and version

Linux 5.15.2-arch1-1 GNU/Linux

Affected language servers

Volar, bash-language-server

Steps to reproduce

1. Create a sample project with npm init vite@latest, picking the vue-ts option.
2. nvim -u minimal.lua src/App.vue

Actual behavior

LSP should not crash, or should show some clues as to what went wrong.

Expected behavior

LSP exits silently with no indicator of what's wrong.

Does it crash non-containerized? If the answer is no, this belongs on our discourse.

[WhyNotHugo]

Sorry, I didn't actually mention this here: my question is how to debug this further. I don't mind attempting to address this myself, but am kinda stuck trying to figure out how to debug in LSP in general.

I haven't tried in a non-containerised context; haven't gotten around to setting up a suitable environment for that.

Sorry, I didn't actually mention this here: my question is how to debug this further.

And the point is that such questions don't belong on a bug tracker, sorry. Use the Discourse link from the issue template or ask on Matrix.

[clason]

(If it turns out to be a bug in lspconfig, feel free to edit the issue and reopen or ping a maintainer to do it.)

[WhyNotHugo]

For anyone curious on this, it turned out to be related to https://github.com/microsoft/vscode-languageserver-node/issues/857. https://github.com/lspcontainers/lspcontainers.nvim/pull/49/files has further details.
