 *  Fix: Don't include potentially-sensitive header values in `Headers.toString()` or exceptions.
    This applies to `Authorization`, `Cookie`, `Proxy-Authorization`, and `Set-Cookie` headers.
 *  Fix: Don't crash with an `InaccessibleObjectException` when running on JDK17+ with strong
    encapsulation enabled.

Standardmäßig verwendet **FastAPI** eine strikte Prüfung des `Content-Type`-Headers für JSON-Requestbodys. Das bedeutet, dass JSON-Requests einen gültigen `Content-Type`-Header (z. B. `application/json`) enthalten MÜSSEN, damit der Body als JSON geparst wird.
