Hi @kaplansin
We tried to reproduce it but were not able to do this for now. Could you be able to try to reproduce this issue on https://public.postnlmagento2.hypernode.io ? If it's reproduced - please give us the first order number that you placed before error 500.

Your PR does makes sense, but it seems like the reason why the "date" is empty should go from the incorrect response in the first place and we would like to see why it ends up that way.
