because the path parameter `item_id` had a value of `"foo"`, which is not an `int`.

The same error would appear if you provided a `float` instead of an `int`, as in: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

So, with the same Python type declaration, **FastAPI** gives you data validation.

Sehen wir uns an, was jede dieser Optionen bedeutet:

* `main:app`: Das ist die gleiche Syntax, die auch von Uvicorn verwendet wird. `main` bedeutet das Python-Modul mit dem Namen `main`, also eine Datei `main.py`. Und `app` ist der Name der Variable, welche die **FastAPI**-Anwendung ist.
    * Stellen Sie sich einfach vor, dass `main:app` einer Python-`import`-Anweisung wie der folgenden entspricht:

        ```Python

		writeErrorResponseJSON(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

	buckets := make([]string, 0, len(bucketInfos))
	for _, bInfo := range bucketInfos {
		buckets = append(buckets, bInfo.Name)
	}

	var id string
	if id, err = pools.initRebalanceMeta(ctx, buckets); err != nil {
		writeErrorResponseJSON(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}
