我正在使用"angular-tree-component": "^8.0.3"为我的 Angular7 单页应用程序（SPA）构建树。我正在关注文档并创建树，但是一旦向组件中的节点提供输入，就会出现以下异常。

core.js:14597 ERROR Error: Uncaught (in promise): TypeError: Cannot add property uuid, object is not extensible

    at TreeNode.setField (tree-node.model.js:179)

    at MapSubscriber.Subscriber.next (Subscriber.js:54)
    at DistinctUntilChangedSubscriber._next (distinctUntilChanged.js:54)
    at DistinctUntilChangedSubscriber.Subscriber.next (Subscriber.js:54)

无论是否正确地完全数据没有复制到节点或任何其他类型的问题，这背后的原因可能是什么。请任何人帮助。谢谢。
