Can't Connect Front end Code to Back end

[vivekananthan28]

Hello sir, The Instructions about how to run front-end code are very well and it is working, however, but for the backend using mongo DB, the instructions are not properly given, and face so many errors while running the backend even after assigning the required credentials to the .env file and it cant be solving and the project is not running. If possible try to provide proper execution instructions in the Readme.MD file for the backend API code and by any chance try to make a demo video to utilize this project properly. Thank you sir.
