### Override request validation exceptions { #override-request-validation-exceptions }

When a request contains invalid data, **FastAPI** internally raises a `RequestValidationError`.

And it also includes a default exception handler for it.

To override it, import the `RequestValidationError` and use it with `@app.exception_handler(RequestValidationError)` to decorate the exception handler.

        // Then
        // The writeBytesWireFormat writes the structure and calculates padding
        // Base structure: 24 bytes, then pad8 alignment, then token: 5 bytes
        // Total bytes written includes padding for 8-byte alignment
        int expectedBytesWritten = 35;
        assertEquals(expectedBytesWritten, bytesWritten);

        // Verify structure

// MetricsGroup - represents a group of metrics. It includes a `MetricsLoaderFn`

Because all the **fields actually change** (the type now includes `None` and they now have a default value of `None`), we need to **re-declare** them.
