I am getting error while calling REST API endpoint. It looks like this is caused by the middleware "django.middleware.clickjacking.XFrameOptionsMiddleware". we have configured clickjacking middleware in django project like below. We were not getting this error while using Django 2.0.4. But now we have upgraded django version to 4.0.6. After the upgrade, we started getting this error while calling REST API endpoint. Unable to understand why Response object won't have header attribute. Refer below exception log

HttpResponse.headers was added in Django https://docs.djangoproject.com/en/3.2/ref/request-response/#django.http.HttpResponse.headers
DRF's Response inherits from Django's.

Maybe you have a cached response?

Either way, Trac is for issues reports in Django. Please see TicketClosingReasons/UseSupportChannels for appropriate support channels.
