Steps to reproduce

1. Update to Nextcloud 31.0.10
2. Extract the twofactor_gateway.tar.gz to /custom_apps/twofactor_gateway
3. Enable the App and and reload Nextcloud

Expected behaviour

It should work like the Previous Version v0.20.0

Actual behaviour

Nextcloud stops to function and this appears in the Nextcloud Log:
