We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Flatpages and Redirects broken when using ASGI
Examples:

- https://grand-challenge.org/about/ (flatpage, exists)
- https://grand-challenge.org/about (should redirect to https://grand-challenge.org/about/)
- https://parse2022.grand-challenge.org/Participation (should redirect to https://parse2022.grand-challenge.org/Participation/)
- https://parse2022.grand-challenge.org/gfsdfgdfdsg (should redirect to https://parse2022.grand-challenge.org/gfsdfgdfdsg/, which should 404).

Error occurs in the clickjacking middleware:
