How can I debug a NodeJS application in IntelliJ Idea?

Question

I have a NodeJS project with a package.json file that contains following lines:

"scripts": {
  [...]
  "start:dev": "cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js",
  [...]
}

I can start the program in the command line using npm run start:dev.

Now I want to debug some of the code. For this purpose I created a NodeJS Run configuration in Idea with the following parameters (pasted cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js into Node Parameters).

When I run it, I get the following error:

/usr/bin/node cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js
Debugger listening on ws://127.0.0.1:43392/5a2c1e8e-a508-4578-8eb0-2bc4f4a63b30

What do I need to change in order to be able to start the application in Idea and debug it?

Found the answer. You need to click the green arrow next to the script definition (next to the line numbers 8 and 9):

There you can select whether to run or debug the script.
