Nehmen wir an, dass die Datei `main.py` mit Ihrer **FastAPI**-Anwendung jetzt einige andere **Pfadoperationen** hat.

Sie verfügt über eine `GET`-Operation, die einen Fehler zurückgeben könnte.

Sie verfügt über eine `POST`-Operation, die mehrere Fehler zurückgeben könnte.

Beide *Pfadoperationen* erfordern einen `X-Token`-Header.
