I'm not sure if it's by design, but I'm using the legacy service because it faster than the normal service. I have a categorized view and would like to use the 'startkeys' property in combination with a categoryfilter.

It always returns a view navigator error but maybe this is by design. Let me know if this could be fixed or I have to find another way.
 

This is my error :
