CORS issue in Django?

Access to XMLHttpRequest at 'http://127.0.0.1:8000/' from origin 'http://localhost:62570' has been blocked by CORS policy: Request header field access-control-allow-origin is not allowed by Access-Control-Allow-Headers in preflight response.

I have tried adding django-cors-headers middleware and CORS_ALLOW_ALL_ORIGINS = True and I have also made ALLOWED_HOSTS = ['*'] but still getting same CORS error. I had the same error with NestJS but after adding app.enableCors(); it got resolved.

Here is my settings.py file
