/// warning | "Achtung"

Sie können mehrere `File`- und `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der Request den Body mittels `multipart/form-data` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.
