electron-forge-start --vscode

example launch.json did work for me on Windows 10 but didn't work on Catalina.

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Electron Main",
            "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron-forge-vscode-nix",
            "windows": {
              "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron-forge-vscode-win.cmd"
            },
            "runtimeArgs": [
              "foo",
              "bar"
            ],
            "cwd": "${workspaceFolder}"
          }
    ]
}

editing electron-forge-vscode-nix seems to solve the issue:
from:

7: node $DIR/../../../@electron-forge/cli/dist/electron-forge-start --vscode -- \~$ARGS\~

to:

7: node $DIR/../@electron-forge/cli/dist/electron-forge-start --vscode -- \~$ARGS\~

so the full file which works for me is:

#!/usr/bin/env bash
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

ARGS=$@
ARGS=${ARGS// /\~ \~}

node $DIR/../@electron-forge/cli/dist/electron-forge-start --vscode -- \~$ARGS\~
