Neste caso, o cliente irá ver uma resposta *HTTP 500 Internal Server Error* como deveria acontecer, já que não estamos levantando nenhuma `HTTPException` ou coisa parecida, mas o servidor **não terá nenhum log** ou qualquer outra indicação de qual foi o erro. 😱

If it was in a type annotation we could have used the vertical bar, as:

```Python
some_variable: PlaneItem | CarItem
```

But if we put that in the assignment `response_model=PlaneItem | CarItem` we would get an error, because Python would try to perform an **invalid operation** between `PlaneItem` and `CarItem` instead of interpreting that as a type annotation.
