I'm seeing loads of these errors on my bots when running tests (Windows, stable) but as far as I can tell it's not actually affecting the tests.

I'm not sure if it's related, but there's a different error at the bottom there:

Note: I can repro the same locally, it's not isolated to the bots.

[roblourens]

FYI @connor4312 the 'item' error deminifies to here

[andrew-laughlin]

I can repro a related error fairly consistently. I say "fairly" because sometimes debugging works, and I don't know why. i.e. My breakpoints get hit, as opposed to saying "unverified breakpoint". I'm writing PHP and have the XDebug v1.34.0 (PHP Debug) extension installed.

Version: 1.85.1
Commit: 0ee08df
Date: 2023-12-13T09:47:11.635Z
Electron: 25.9.7
ElectronBuildId: 25551756
Chromium: 114.0.5735.289
Node.js: 18.15.0
V8: 11.4.183.29-electron.0
OS: Linux x64 5.10.0-27-amd64

Repro steps:

1. In VSCode click "Listen for Xdebug" to launch a debug session. Debug console shows ... "Listening to Xdebug on port 0.0.0.0:9003 ..."
2. Manually click an item in the web browser. The browser connects to Local (which hosts a Wordpress site) and connects to Xdebug.
3. Sometimes the breakpoints will hit. More often than not however, once the browser makes the request, I get the following error in the VSCode dev tools:

I'm continuing here from #202003. I've setup a Linux VM to help me analyze the issue. As reported there are two thrown errors (Invalid debug adapter) that happen in getDebugAdapter first as a result of $acceptDAExit and second because of $acceptDAError.

Poking a bit around git history I think the problem comes from removing the _debugAdapters entry too early.

In my case, the events go roughly like this:

1. User clicks stop debug
2. actionbar actionViewItem onClick fires and calls debugCommands stopHandler
3. stopHandler calls debugSession.stopSession
4. calls DebugSession.terminate
5. calls RawDebugSession.disconnect
6. calls RawDebugSession.shutdown
7. calls RawDebugSession.stopAdapter and then fireAdapterExitEvent
8. calls DebugSession.onDidExitAdapter
9. calls onDidEndAdapter in DebugService
10. calls onDidEndSession in MainThreadDebugService that deletes the debug adapter.

This is then followed by RPC calls like $acceptDAError (some socket read error). $acceptDAExit (normal exit of the DA process) that all result in errors because the debug adapter object is gone.

Where to actually delete the entry is beyond me - unless I invest more time into understanding the whole debug service and main proc/ext host architecture...

Hope this helps.

FWIW, I feel like this is happening a lot more lately. I see it both in Dart projects and TypeScript (VS Code extension) projects. When it happens, the debug toolbar disappears even when I'm in a debug session, and pressing F5 no longer starts a new session (I have to use the menu or button on the sidebar).
