YOu should not use the MiddlewareMixin, the MiddlewareMixin is for the old-style middleware, but you are writing this in the new way, so:

class TokenMiddleware:  # !L! no MiddlewareMixin
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        authorization = request.META.get('HTTP_AUTHORIZATION')
        if authorization and authorization.startswith('Bearer '):
            token = authorization.split(' ')[1]
            jwks_client = jwt.PyJWKClient(settings.JWT_VERIFY_URL)
            header = jwt.get_unverified_header(token)
            key = jwks_client.get_signing_key(header['kid']).key
            try:
                jwt.decode(token, key, [header['alg']])
            except jwt.ExpiredSignatureError:
                return JsonResponse({'error': 'Token has expired'}, status=401)
            except jwt.DecodeError:
                return JsonResponse({'error': 'Token is invalid'}, status=401)
        else:
            return JsonResponse(
                {'message': 'Authentication Bearer Token is required.'}
            )
        return self.get_response(request)

As for the DRF, your TokenMiddleware is not an authentication class, but likely not necessary here anyway, since it will go through the middleware. You thus remove this from the AUTHENTICATION_CLASSES:

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        # 'my_app.middleware.TokenMiddleware',  # 🖘 remove
    ],
    # …
}

I see configuration you shown indicates that you added TokenMiddleware both to the MIDDLEWARE and REST_FRAMEWORK[‘DEFAULT_AUTHENTICATION_CLASSES’]. This is the problem.

If TokenMiddleware is supposed to be middleware:

Remove ‘my_app.middleware.TokenMiddleware’ from the DEFAULT_AUTHENTICATION_CLASSES in REST_FRAMEWORK.
If TokenMiddleware is supposed to be an authentication class:

Remove ‘my_app.middleware.TokenMiddleware’ from the MIDDLEWARE.
