Description

With recent versions of opencode >= 1.0.46, there appears to be a race condition when bun attempts to install packages from package.json in .opencode. We have some custom plugins that no longer function unless we manually do a npm install in the .opencode directory.

Issue:

18:52:01 +8ms - bun add fails (error code 1) - "An unknown error occurred (Unexpected)"
18:52:01 +417ms - bun add succeeds (code 0) - "@opencode-ai/plugin@1.0.40 installed"
18:52:01 +4ms - Plugin loading starts (dynamic-context-loader.ts)
18:52:01 +11ms - ERROR: Cannot find module '@opencode-ai/plugin'

Timeline Analysis:

  1. First bun add attempt fails (exits immediately at +8ms)
  2. Second bun add attempt succeeds (takes 423ms, completes at +417ms)
  3. Plugin loading starts at +4ms (only 4ms after initial failure!)
  4. Import fails at +11ms (7ms later)

The Problem:

The successful bun add at +417ms is too late - plugin loading already started at +4ms.

  1. Concurrent execution - installDependencies() not awaited
  2. Plugin loader doesn't wait - Starts importing before dependencies installed
  3. Race condition - Even when install succeeds, timing is unpredictable

OpenCode version

1.0.46

This issue might be a duplicate of existing issues. Please check:

  • #4047: Both involve bun installation failures and plugin loading issues with similar error patterns
  • #4126: Same "Cannot find module" error when dependencies are missing during build/load process

Feel free to ignore if none of these address your specific race condition case.

I didn't mention I was running on WSL, which is solved by using WSL 2.0
