Your script is not written correctly, it "glues" lines together and you get this: servernpm run client. Change it to:

"dev": "concurrently \"npm run server\" \"npm run client\""

Sir, thank you a lot. I does really work. COuld not even have thought that spaces play a big role in this case. Good luck and thanks again!

I have the same configurations. How can we use this to debug the front and backend concurrently? What would be the launch setting configuration to debug both together?
