How to use the azure-servicebus.azure.servicebus._common_error._ERROR_TOPIC_NOT_FOUND function in azure-servicebus

if topic_element is not None:
        mappings = [
            ('DefaultMessageTimeToLive', 'default_message_time_to_live', None),
            ('MaxSizeInMegabytes', 'max_size_in_megabytes', int),
            ('RequiresDuplicateDetection', 'requires_duplicate_detection', _parse_bool),
            ('DuplicateDetectionHistoryTimeWindow', 'duplicate_detection_history_time_window', None),

            ('SizeInBytes', 'size_in_bytes', int),
        ]

        for map in mappings:
            if _read_etree_element(topic_element, map[0], topic, map[1], map[2]):
                invalid_topic = False

    if invalid_topic:
        raise WindowsAzureError(_ERROR_TOPIC_NOT_FOUND)

    # extract id, updated and name value from feed entry and set them of topic.
    for name, value in _ETreeXmlToObject.get_entry_properties_from_element(
        entry_element, True).items():
        setattr(topic, name, value)
