This may be due to the following script:

Just going to generalise my original comment: something that was [] Array is now an object. Possibly a Float32Array, but could also be an object like Record<number, any>.

So LGraphNode.pos is Float32Array internally - I think it might have been for a while. There's an old-style getter/setter combo in litegraph to prevent consumers from overwriting its reference.
