TYPO3 扩展库:无法创建类的空实例.对象存储

我在extbase extension creation期间在我的项目中遇到以下 TYPO3 错误

Cannot create empty instance of the class
"TYPO3'CMS'Extbase'Persistence'ObjectStorage" because it does not implement
the TYPO3'CMS'Extbase'DomainObject'DomainObjectInterface.

我认为这与从另一个扩展rezepte加载对象有关。

'rezepte' => array(
        'exclude' => 0,
        'label' => 'LLL:EXT:nebenwirkungen/Resources/Private/Language/locallang_db.xlf:tx_nebenwirkungen_domain_model_nebenwirkung.rezepte',
        'config' => array(
            'type' => 'select',
            'foreign_table' => 'tx_rezepte_domain_model_rezept',
                            'foreign_table_where' => 'AND tx_rezepte_domain_model_rezept.sys_language_uid=###REC_FIELD_sys_language_uid### ORDER BY tx_rezepte_domain_model_rezept.rezeptname',
            'MM' => 'tx_nebenwirkungen_nebenwirkung__mm',
            'size' => 10,
            'autoSizeMax' => 30,
            'maxitems' => 9999,
            'multiple' => 0,
            'wizards' => array(
                '_PADDING' => 1,
                '_VERTICAL' => 1,
            ),
        ),
    ),

任何想法可能出了什么问题？
