Der Client erhält für diesen Request einen **500 Internal Server Error**, aber die Anwendung arbeitet bei den nächsten Requests weiter, anstatt einfach komplett abzustürzen.

### Größere Fehler – Abstürze { #bigger-errors-crashes }

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

The client will get a **500 Internal Server Error** for that request, but the application will continue working for the next requests instead of just crashing completely.
