   I am not sure about the root cause of this, but some time ago we merged something like this in arrow2, could you check if https://github.com/jorgecarleitao/arrow2/pull/194, specifically around `write_generic_binary` in `src/io/ipc/write/serialize.rs` is what we are looking for here?
   
   Note that the code is significantly different at this point, but the gist is that we need to check if the array was sliced, and if it was, only write the relevant values.
