Not able to debug Azure Functions in Visual Studio Code

I am trying to do this tutorial to run azure function app using vs code.

I am able to run it locally, but not debug it.

When I browse to localhost:7071/api/category, I am getting the response.

But I place a breakpoint(see the above image on line 11), it is supposed to stop, but does not.

I see a difference in the image shown here in the docs with mine.

Contrast to that, I see a square in my case (see below). Does this make a difference?

Update

Azure Function core tools are already installed. Still the problem

Update 2

Its probably the version of Azure Function Core Tools

At least with C# Azure Functions, when ever I have 4.x, I am able to debug.

This morning I started with this tutorial. And if you scroll down a bit, its clearly mentioned 4.x here

I downloaded 4.x and well as 3.x installers, installed, uninstalled, and then re-installed and checked. I see that, at least with C#, I am able to debug with 4.x. But with javascript, I still facing some issues.

The article here tells us to install Azure Functions Core Tools V3. This could probably wrong and must be revisited.

I just saw here, with JavaScript, its further complicated by the Node js version on my machine. In here, it says Node.js 10.14.1+, while on my machine, its v14.17.3 while the LTS is at v16.
