Wenn ein Client versucht, einige **zusätzliche Header** zu senden, erhält er eine **Error-<abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>**.

Zum Beispiel, wenn der Client versucht, einen `tool`-Header mit einem Wert von `plumbus` zu senden, erhält er eine **Error-Response**, die ihm mitteilt, dass der Header-Parameter `tool` nicht erlaubt ist:

```json
{
    "detail": [
