I should add the steps needed to use vscode to debug.

1. Clone the jscad cli repo
2. Do an npm install
3. Create a standard launch profile for node.

Here is my launch.json file ...

 "version": "0.2.0",
  "configurations": [

    {
      "type": "pwa-node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": [
        "<node_internals>/**"
      ],
      "program": "node_modules/@jscad/cli/cli.js",
      "args": ["text-gen.js"]
    }
  ]
}

After this I just set a breakpoint in my jscode and launched the debugger. Worked great.

P.S. If anyone is curious I was able to fix my vectorChar problem. It was in my code but I was only able to find my problem by using the debugger.

I found the answer to my problem right after posting this. I tried forever to figure this out before posting. This seems to happen to me a lot.

For lurkers: The "program" option in the launch file should be "node_modules/@jscad/cli/cli.js"
