helix-gpt: [BUG] failed to initialize language server: request 0 timed out

device info Apple M2 Pro

helix-editor version helix 23.10 (1d1806c8)

helix-gpt version 0.31

Describe the bug The initialization request from Helix times out when opening a file for which helix-gpt is configured to run. helix-gpt waits in src/models/lsp.ts in line 207 for Chunks from. Bun.stdin.stream() but nothing ever arrives. I checked this by logging the chunkText.

If I start helix-gpt manually with

echo "Hello Helix-GPT" | bun run /Users/xaver.himmelsbach/Development/helix-gpt/src/app.ts --logFile /Users/xaver.himmelsbach/gpt.log

the input is read from stdin:

APP 2024-03-19T16:45:21.209Z --> triggerCharacters: | ["{","("," "]

APP 2024-03-19T16:45:21.213Z --> Hello Helix-GPT

APP 2024-03-19T16:45:21.214Z --> failed to parse line:| failed to parse | Hello Helix-GPT

helix-gpt logs Most of the time, helix-gpt justs prints the triggerCharacters and receives nothing more. Sometimes, when repeatedly executing :lsp-restart in Helix, an initialization request comes through, but that still doesn’t seem to be handled correctly.

These logs show the request showing up after repeatedly calling :lsp-restart:

helix logs Helix seems to send the initialization request and times out after 10 seconds (default LSP timeout). Increasing the timeout in languages.toml just led to longer waiting times.
