This client could be a browser with a frontend, a code from someone else, an IoT device, etc.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

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

The good news is, in most cases, you will be able to simply use `|` to define unions of types:

```python
def say_hi(name: str | None):
    print(f"Hey {name}!")
```
