unknown error: call function result missing int 'status'

Context

I’m trying to launch a VS Code window using Spectron. Here’s the setup:

  app = new Application({
    path: vscodeExecutablePath,
    args: [
      "--no-sandbox",
      "--disable-updates",
      "--skip-welcome",
      "--skip-release-notes",
      "--disable-workspace-trust",
      `--extensionDevelopmentPath=${extensionPath}`,
    ],
    requireName: "nodeRequire",
  });

The VS Code version I’m launching is 1.66.2 with the following environment:

ersion: 1.66.2 (Universal)
Commit: dfd34e8260c270da74b5c2d86d61aee4b6d56977
Date: 2022-04-11T07:49:20.994Z (1 wk ago)
Electron: 17.2.0
Chromium: 98.0.4758.109
Node.js: 16.13.0
V8: 9.8.177.11-electron.0
OS: Darwin arm64 21.2.0

I confirm that vscodeExecutablePath is correct as I see the window launching. Yet the app.start() throws the following error:

Dependencies

{
  "spectron": "19.0.0"
}

Transient dependencies:

  └─┬ spectron@19.0.0
    └── webdriverio@7.16.13

  └─┬ spectron@19.0.0
    └── electron-chromedriver@17.0.0

Things I’ve tried

• Ensured I’m using the correct Spectron version in regards to the Electron version I’m trying to render.
• Ensured I’m using the correct chromedriver (you can see in the error trace that the version of the chromedriver and the Chromium version used by VS Code are the same).

Expected behavior

I can launch the given VS Code executable without issues.

@kettanaito we’re not likely to get replies from the maintainers as Spectron is deprecated (https://github.com/electron-userland/spectron/issues/1045) but I’ll definitely return here if I figure something out on my end.

Hey, @arossetter. Alas, I’m stuck on this as well. Sadly, there’s been no replies from the project’s maintainers. I’d really love to hear some suggestions on how to debug this at least. Same here: if you find anything that moves you forward please let me know!
