Hello
I would like to share a note about the change in DTO behavior on Che master side.
Previously in during DTO serialization, we put everything to the output including
empty collections/fields. At this moment we are not able to identify the concrete reason why we did this way and not the opposite.
This behavior brings to us some difficulties when we tried to add devfile schema validation in our REST API.
So we decided to rethink this behavior again. As a result, we think that it makes sense to revert this behavior and do not serialize empty collections/fields. That will allow reducing the size of result json. As a side effect all clients (most of them already doing that)
has to check optional field != null before doing any operation with it.
