Hello Bappaditya,
You need to add CORS middleware to fix this issue. Check out the guide to add middleware in express applications here:-
https://expressjs.com/en/resources/middleware/cors.html
Also try to understand what is Cross-Origin Request from this article when you get time:-

What is CORS? Complete Tutorial on Cross-Origin Resource Sharing

Let me know if there are any other doubts/issue while using the middleware.

CORS already added

used cors

Are you able to access the API in Postman?

And did you redeploy the application after adding cors?
