ReactDiagram uses Model.mergeLinkDataArray() in componentDidMount and componentDidUpdate.
This method pushes users to make key property in linkDataArray, though most of linkDataArray object has no key property.

Yes, if you are using a GraphLinksModel, you must provide a linkKeyProperty, as documented in the readme: https://github.com/NorthwoodsSoftware/gojs-react#initdiagraminitpaletteinitoverview
