When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

::: fastapi.WebSocketDisconnect

## WebSockets - additional classes

 *     ExecutionException}, {@code UncheckedExecutionException}, and {@code ExecutionError}. Any
 *     code that is still catching {@code ComputationException} may need to be updated to catch some
 *     of those types instead. (Note that this type, though deprecated, is not planned to be removed
 *     from Guava.)
