使用AWS Cloud Directory JDK创建对象时遇节点类型判定错误求助

错误信息 #

解决建议 #

• 自定义Facet必须继承Cloud Directory提供的基础节点类型之一：LeafNode、Node、Policy或Index。你的DynamicObjectFacet未继承这些类型，导致服务无法识别对象的节点类别，触发400错误。
• 修改Schema中DynamicObjectFacet的定义，添加对基础节点类型的继承。例如，如果创建的是普通层级节点，继承Node；如果是无子节点的叶子对象，继承LeafNode。
• 确认Schema已经正确发布并关联到目标Directory，代码中使用的Schema ARN准确无误。
• 若Schema已完成基础类型继承，代码中仅需指定自定义Facet即可；若未在Schema中配置继承，也可在创建对象时的schemaFacets中同时包含基础类型Facet和自定义Facet（不推荐，建议在Schema层面完成继承）。
