This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.

But it's the simplest way to focus on the server-side of WebSockets and have a working example:

## Create a `websocket` { #create-a-websocket }

In your **FastAPI** application, create a `websocket`:

    ContainsBothWithMultisetFirst reMultisetFirst = reserialize(multisetFirst);
    assertThat(reMultisetFirst.a.isEmpty()).isFalse();
    // The following NPE is a side effect of our changes to avoid mutating `final` fields.
    assertThrows(NullPointerException.class, () -> reMultisetFirst.z.multiset.isEmpty());

    ContainsBothWithContainsMultisetFirst reContainsMultisetFirst =

### When Things are Difficult

When things are great, everything is easier, so that doesn't need much instructions. But when things are difficult, here are some guidelines.

- Dynamic Resource Allocation (DRA): client-side validation of a ResourceHandle would have accepted a missing DriverName, whereas server-side validation then would have raised an error. ([#124075](https://github.com/kubernetes/kubernetes/pull/124075), [@pohly](https://github.com/pohly))
