Bug: CORS policy error prevents login from netlify.app

[shozabali06]

Hello, I am unable to log in from the live Netlify site.

Steps to Reproduce:

1. Go to https://bugtracker.netlify.app
2. Enter demo credentials.
3. Click "LOG IN".

Actual Behavior:
A "Network Error" message appears.

Error in Console:
The browser console shows a CORS error. The request from https://bugtracker.netlify.app to https://bugtracker-ad.herokuapp.com/login is being blocked.

Access to XMLHttpRequest at 'https://bugtracker-ad.herokuapp.com/login' from origin 'https://bugtracker.netlify.app' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

The server needs to be configured to send the Access-Control-Allow-Origin header for the Netlify domain.
