How to fix Response for preflight is invalid (redirect)?

Question

Django

I get user data through rest
in the console

Failed to load http://127.0.0.1:8000/api/user/username: Response for preflight is invalid (redirect)

If you go to 127.0.0.1:8000/api/user/username api opens and works fine
The data is not displayed
in the django config

CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = (
  'localhost:3000',
)

Where to dig?

Answer 1

Looks like a problem with cors. Either dig django settings, or install some kind of browser extension https://chrome.google.com/webstore/detail/allow-co...
