Debugging doesn't start

[nbros]

After configuring launch.json and hitting F5 in a compiled Cobol file, debugging doesn't start and I see the following error in the Extension host (remote) output:

[error] TypeError: Cannot read properties of undefined (reading 'pid')
	at Timeout._onTimeout (/home/user/.vscode-server/extensions/olegkunitsyn.gnucobol-debug-2.31.37/out/src/mi2.js:477:32)
	at listOnTimeout (node:internal/timers:559:17)
	at processTimers (node: internal/timers:502:7)

How does your configuration look like?

I have installed and configured:

• VS Code, IBM Z Open Editor and COBOL debugger.
• cobc (GnuCOBOL) 3.1.2.0
• GNU gdb (Ubuntu 12.1-0ubuntu1~22.04) 12.1

This is my launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "COBOL debugger",
            "type": "gdb",
            "request": "launch",
            "cobcargs": [
                "-free",
                "-x"
            ],
            "coverage": true
        },
    ]
}

When I press F5 and select "Cobol debugger", als nothing happens.
Is it possible that npm (nodejs) must be installed?

No.

You may have to create a launch.json, if this wasn't done automatically (which would be a bug that should be tracked in a separate issue).

If you have this configuration then you may need to set a breakpoint in your COBOL source to not start, run, finish all in a row.

After adding a folder to the workspace it was possible to create a new launch.json.
But in the launch.json I had to remove the "-free" option. Now it is working.
Thank you for your help.
