...that's because the client generator uses the OpenAPI internal **operation ID** for each *path operation*.

OpenAPI requires that each operation ID is unique across all the *path operations*, so FastAPI uses the **function name**, the **path**, and the **HTTP method/operation** to generate that operation ID, because that way it can make sure that the operation IDs are unique.

     * @param id The ID of the dictionary file.
     * @param path The path of the dictionary file.
     * @param timestamp The timestamp of the dictionary file.
     * @return A new dictionary file.

    @Override
    protected DictionaryFile<? extends DictionaryItem> newDictionaryFile(final String id, final String path, final Date timestamp) {
        return new KuromojiFile(id, path, timestamp).manager(dictionaryManager);
    }

Notice that here as we are using standard `open()` that doesn't support `async` and `await`, we declare the path operation with normal `def`.

### `FileResponse` { #fileresponse }

Asynchronously streams a file as the response.

Takes a different set of arguments to instantiate than the other response types:

* `path` - The file path to the file to stream.
* `headers` - Any custom headers to include, as a dictionary.
