Description

After the latest update to v1.0.180, I get the following crash on startup:

{
  "name": "UnknownError",
  "data": {
    "message": "TypeError: undefined is not an object (evaluating 'Provider2.sort(Object.values(item.models))[0].id')\n    at <anonymous> (src/server/server.ts:1604:95)\n    at o3 (../../node_modules/.bun/remeda@2.26.0/node_modules/remeda/dist/chunk-3ZJAREUD.js:1:137)\n    at <anonymous> (src/server/server.ts:1604:22)\n    at processTicksAndRejections (native:7:39)"
  }
}

I have tried to downgrade to different versions of opencode and now only get this error no matter the version.

OpenCode version

v1.0.180

Steps to reproduce

  1. Install opencode v1.0.180
  2. Run opencode to start a new session
  3. Get this crash

Screenshot and/or share link

No response

Operating System

macOS 15.7.1

Terminal

Ghostty w/ zsh

@github-actions[bot] commented on GitHub (Dec 20, 2025):

I've searched through existing issues in this repository and did not find any clear duplicates of this issue. The error you're encountering appears to be unique to the Provider sorting logic in v1.0.180.

However, this is a startup crash issue, so if you've seen similar crashes in the past, you may want to check if any of these startup-related issues contain helpful troubleshooting steps:

  • #3537: Custom slash commands can crash opencode on startup
  • #3568: "Unexpected EOF" crash immediately after startup
  • #5338: Opencode becomes stuck on start if internet connection is not stable

If downgrading to previous versions still causes the crash, it might indicate a configuration corruption. You could try clearing your state directory at ~/.local/state/opencode/tui or your config directory to see if that resolves the issue.

I get the issue on 1.0.150. It looks like models.json got changed (sidenote: how) to have an invalid schema via some out of band process, which is causing the crash.

@SimHoZebs commented on GitHub (Dec 20, 2025):

Seems to be fixed now from models.dev fix. The issue was with one of the model providers in models.dev not actually including a model. Opencode expects so and crashes otherwise (hence Provider2.sort(Object.values(item.models))[0] being undefined). Not sure if that's type safe?
