## Override the default exception handlers { #override-the-default-exception-handlers }

**FastAPI** has some default exception handlers.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

participant client as Client
participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation
participant tasks as Background tasks

    Note over client,operation: Can raise exceptions, including HTTPException
    client ->> dep: Start request
    Note over dep: Run code up to yield
    opt raise Exception
        dep -->> handler: Raise Exception

            Handler handler2 = new Handler();
            Handler handler3 = new Handler();

            // Then
            assertEquals(443, handler1.getDefaultPort());
            assertEquals(443, handler2.getDefaultPort());
            assertEquals(443, handler3.getDefaultPort());
        }
