VSCode debug is not working on current file but on another file

I’m using VSCode 1.33.0 on Mac.
Had created file ES6.js and later created RegularExpress.js.

When I try to debug code in RegularExpress.js., debugger always goes to ES6.js. This is very strange.

Please check attached screenshot.

Got it working as per solution mentioned under https://stackoverflow.com/questions/38419779/debugging-current-file-in-vs-code
