i've tried

• reinstalling
• remove all packages then reinstalling again
• change django-cors-headers @ https://github.com/adamchainz/django-cors-headers/archive/main.zip to django-cors-headers then reinstalling

but still got this error, here the screenshoot

when i removing corsheaders from settings.py everything is fine, except the cors header for non-origin/external calls.

Hi I have the same problem. The issue seems to be in the signal.py file:

import django.dispatch

# Return Truthy values to enable a specific request.
# This allows users to build custom logic into the request handling
check_request_enabled = django.dispatch.Signal(
    providing_args=["request"]
)

When I change it to this:

import django.dispatch

# Return Truthy values to enable a specific request.
# This allows users to build custom logic into the request handling
check_request_enabled = django.dispatch.Signal(["request"])

it works for me.
