How to attach debugger to ts-node command with env vars in VSCode

[GorvGoyl]

How to attach the VSCode debugger to the ts-node command that uses env variables like the below one:

package.json:

{
"runMyScript": "ts-node -r dotenv/config --transpile-only tasks/migration/myScript.ts dotenv_config_path=./local.env"
}

I tried adding flags --respawn --inspect=4000 to the above command with below launch.json, but it didn't work:

launch.json:

{"configurations": [
    {
      "name": "RUN attach to DEV",
      "type": "node",
      "port": 4000,
      "request": "attach",
      "trace": true,
      "skipFiles": ["<node_internals>/**"],
      "restart": true
    },
