Nuitrack.GetInstancesJson from .ONI file not work

I’am trying get emotion by Nuitrack.GetInstancesJson metod.
For test use unity '‘animated empji’ proj.
When i use a real camera(RS d415) it’s works perfect, but when i use .ONI file, recived by the same camera, i see image(RGB) from the file stream but face not recognize.
Maybe I didn’t catch all the layers in NiViever?
