Opening the UAST viewer (individual, with the UAST button), and then performing a search, e.g. //*, produces this error in the console. It might happen only during the loading phase, as it then renders correctly.

index.js:2178 Warning: Failed prop type: The prop `id` is marked as required in `Node`, but its value is `undefined`.
