IntelliJ debugger is connected to Firebase local emulator but doesn't stop at breakpoints

I've been at this for days on and off. Read through and followed all threads on the subject i could find but still can't get this to work.

I'm trying to debug Firebase functions locally in IntelliJ IDE. Here's the output of start command.

**firebase emulators:start --inspect-functions**

The debugger configuration is set attached to Chrome/Node on port 9229 and appears to be working fine. However when i set breakpoints and call the testFunction by opening a browser to http://127.0.0.1:5001/test-project/europe-west1/testFunction the function runs and shows its output of external ip address without stopping at the breakpoints. Is there a special way to call the Firebase emulator function in order to envoke the debugger? What am i missing? Please help.

From https://medium.com/@david_shortman/build-and-debug-firebase-functions-in-vscode-73efb76166cf, Using Firebase Functions from a Webpage in Javascript section I can see that such functions have to be debugged in a different way; you likely have to use JavaScript Debug run configuration (see Debugging a Webpage with Chrome debugger at the bottom of the page). Didn't try it myself though. Can you check if you can debug your functions in Chrome Dev Tools, for example? if it works, then debugging with JavaScript Debug run configuration should work as well

I'd also suggest asking a question at Firebase Google Group
