> Schema pruning tries to extract selected fields from struct extractors. It looks through GetArrayItem/GetMapItem, but when doing so, it ignores the index/key, which may itself be a struct field. If it is a struct field that is not otherwise selected, and some other field of the same attribute is selected, then pruning will drop the field, resulting in an optimizer error.
