Could using the optic's `copy { }` function lead to a `Caused by: java.lang.NullPointerException: Parameter specified as non-null is null: method .....&lt;init&gt;, parameter details` error for some reason? None of the constructor params are coming from Java... and they're all initialized with default params...

It seems like it happens when what I'm copying from is top-level, but when I put it in the test class, it works :thinking_face:...
