The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:

```Python
say_hi(name=None)  # This works, None is valid 🎉
```

The good news is, once you are on Python 3.10 you won't have to worry about that, as you will be able to simply use `|` to define unions of types:

     */
    @Override
    public CommonServerMessageBlockRequest createCancel() {
        return new Smb2CancelRequest(getConfig(), getMid(), getAsyncId());
    }

    /**
     * {@inheritDoc}

    @Override

        return rootCause;
    }

    @Override

        if (rootCause != null) {
            final StringWriter sw = new StringWriter();
            final PrintWriter pw = new PrintWriter(sw);
            rootCause.printStackTrace(pw);
            return super.toString() + "\n" + sw;
        }
        return super.toString();
