check if you have a valid mongodb connection string in your config.env file (Backend> Config> config.env) For eg: (Your config.env should have valid values for all the below variables (assuming you have local version of Mongodb)

PORT= NODE_ENV= DB_URI=mongodb://localhost:27017/ STRIPE_API_KEY= STRIPE_SECRET_KEY= JWT_SECRET= JWT_EXPIRE= COOKIE_EXPIRE= SMPT_SERVICE= SMPT_MAIL= SMPT_PASSWORD= SMPT_HOST= SMPT_PORT= CLOUDINARY_NAME= CLOUDINARY_API_KEY= CLOUDINARY_API_SECRET=
