Uncaught (in promise): TypeError: Cannot add property uuid, object is not extensible

Question

I am using "angular-tree-component": "^8.0.3" to construct tree for the mine Angular7 Single Page Application(SPA). I am following the documentation and creating tree but getting the following exception onces providing input to nodes in component.

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

what might be the cause behind this whether correctly fully data is not replicating to node or some any other type of issue. Please any one help. Thanks.
