WARNING
Issues caused by **Release 2.0.0 breaking changes** continue to be logged. Please **make sure to carefully read these release notes** before
performing a MAJOR upgrade to 2.x.
These issues both result in `{"error": "invalid_client"}`:
1. The application client secret is now hashed upon save. You must copy it before it is saved. Using the hashed value will fail.
2. `PKCE_REQUIRED` is now `True` by default. You should use PKCE with your client or set `PKCE_REQUIRED=False` if you are unable to fix the client.
