Review Comment:
The issue is that we cannot directly convert a generic Object (data) to
bytes using getBytes(StandardCharsets.UTF_8) unless the object is a String or
implements such a method. The issue here is caused by UnsafeRow object, so I am
adding that specifically but keep the rest (unknown types) cast to string and
getBytes.
