you only need delete your database in mongodb of product and users, in any case delete all and create it again restarting the application.

[mohitshahu108]

check whether your API is working properly
by using the postman tool
if it is then check your database is created or not

by running the command on terminal: mongo
use amanzona
then show collection products

if exist
check did you have imported products from redux store in the file where you tried to use product.
