Vscode: Cannot start debugging electron app on MacOS

[lini]

• VSCode Version: 1.47.0
• OS Version: MacOS 10.14.6
• Node version: 10.x

Steps to Reproduce:

1. Try to launch an electron app with debugging
2. The launch fails because it cannot find part of a path.

Launch.json for the command:

      "name": "Debug Electron",
      "type": "node",
      "request": "launch",
      "program": "${workspaceFolder}/src/main.ts",

      "args": [
        "--param1=http://localhost:1234/",
        "--param2=http://localhost:4200"
      ],
      "cwd": "${workspaceFolder}/out",
      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
      "windows": {
        "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
      },

      ],
      "sourceMaps": true,
      "outFiles": [

      ],
      "console": "integratedTerminal",
      "internalConsoleOptions": "openOnSessionStart",
      "preLaunchTask": "prepare-electron-debug"
}

EDIT: Updating version of Node.js to v12 seems to fix the issue.

Does this issue occur when all extensions are disabled?: Yes, same behaviour when launching with disabled extensions

[e-tip]

Have same issue, but with a different environment and launch options

VSCode Version: 1.47.0
OS Version: MacOS 10.15.5

Launch.json

{
            "type": "node",
            "request": "launch",
            "name": "Core",
            "runtimeExecutable": "nodemon",
            "program": "${workspaceFolder}/app.js",
            "args": [ "--trace-deprecation", "-a", "api"],
            "restart": true,
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen",
            "skipFiles": [
                "<node_internals>/**",
                "${workspaceFolder}/node_modules/**/*.js"
            ]
        }

and this is the error message

i've also tried to solve the issue changing the app name from Visual Studio Code.app to Code.app and relaunching my debug session but i get also an error

Downgraded to version 1.46.1 and everything worked correctly

[gjsjohnmurray]

Looks like #101996

[lini]

Thank you! Updating nodejs from v10 to v12 fixed the issue.

Thank you! Updating nodejs from v10 to v12 fixed the issue.

not work(v12.14.1)

[andyboyne]

This exact issue also happens on windows. Running node 14 so it's not the node version.

[weinand]

Workaround is to use the old node-debug with this setting: "debug.javascript.usePreview": false

Thanks for the issue! Please see https://github.com/microsoft/vscode/issues/102035#issuecomment-656384728

Thanks for creating this issue! We figured it's covering the same as another one we already have. Thus, we closed this one as a duplicate. You can search for existing issues here. See also our issue reporting guidelines.

Happy Coding!

[connor4312]

@lini can you please also confirm which version of electron you were using?

[lini]

The project is using electron 8.2.0

[connor4312]

Okay, thanks. Just saw your edit that updating to Node 12 fixed it.

[connor4312]

A fix for this issue has now been released in VS Code 1.47.2. If you previously had to opt-out of the new debugger, you should be safe to turn it back on. Thanks again for the report!
