This last path operation will have the combination of tags: `["items", "custom"]`.

And it will also have both responses in the documentation, one for `404` and one for `403`.

## The main `FastAPI` { #the-main-fastapi }

Now, let's see the module at `app/main.py`.

Here's where you import and use the class `FastAPI`.

            case 404:
                if (logger.isDebugEnabled()) {
                    logger.debug("Object not found: bucket={}, path={}", bucketName, path);
                }
                break;
            case 403:
                throw new CrawlingAccessException("Access denied: bucket=" + bucketName + ", path=" + path, e);
            default:

				result.MaxValiditySeconds, minValidityDurationSeconds, maxValidityDurationSeconds)

		return AuthNResponse{
			Success: &result,
		}, nil

	case 403:
		var result AuthNErrorResponse
		if err = json.NewDecoder(resp.Body).Decode(&result); err != nil {
			return AuthNResponse{}, err
		}
		return AuthNResponse{
			Failure: &result,
		}, nil

	default:

		// mean that authentication succeeded, but another
		// side-channel check has failed, we shall take
		// the client offline in such situations.
		// generally all implementations should simply return
		// 403, but in situations where there is a dependency

		// fully it should make sure to respond with '412'
		// instead, see cmd/storage-rest-server.go for ideas.

## Das Haupt-`FastAPI` { #the-main-fastapi }

Sehen wir uns nun das Modul unter `app/main.py` an.

Hier importieren und verwenden Sie die Klasse `FastAPI`.
