onCanvasDrop creates two nodes

[Livshind15]

because of React.StrictMode setState updaters will run twice in strict mode in development, This causes a double call to onCanvasDrop function and create double node

Yes I was experiencing the same issue. When structuring my components differently from the examples, the on Node Dropped event is called 2 times.

@MrBlenny I noticed the error occurring when I started to useContext() for the state of my graph according to this example.

When I used this model for the state of the graph, I couldn't figure out how to update the state of the graph from the node, but I did not experience this error.
