Kibana does not show the data of elastiknn_sparse_bool_vector about elastiknn

Hi, I haven't tested with Kibana in a very long time. I suspect I might've broken some part of the internal API that's used by Kibana at some point. If you'd like to take a look, a good starting point would be these methods in the VectorMapper.scala file that are returning empty lists/arrays, e.g.:

• https://github.com/alexklibisz/elastiknn/blob/main/elastiknn-plugin/src/main/scala/com/klibisz/elastiknn/mapper/VectorMapper.scala#L82-L87
• https://github.com/alexklibisz/elastiknn/blob/main/elastiknn-plugin/src/main/scala/com/klibisz/elastiknn/mapper/VectorMapper.scala#L141

I recommend following the instructions for running w/ a debugger: https://github.com/alexklibisz/elastiknn/blob/main/developer-guide.md#debugging
, setting some breakpoints in these methods, and then use kibana to try to access the docs. See which methods get called and how they might be filled in.
