Martin Grund commented on SPARK-41815:

The reason seems to be that when Spark Connect serializes the data to Arrow
it's serialized as `null` and when converted to pandas it will convert this to
the `np.nan` instead of `None`. It seems that we should manually convert `nan`
to `None` for the `Row` type.
