      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }
  ]
}
```

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

```JSON

      "loc": [

      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }
  ]
}
```

porque el parámetro de path `item_id` tenía un valor de `"foo"`, que no es un `int`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.
