Resolution Note (2020.2.X):
The BatchRendererGroup GetBatchVectorArray (and similar functions) work only with ShaderGraph properties. Your project is using the built-in pipeline. You need to install URP or HDRP and ShaderGraph. Then you need to create ShaderGraph shader and add a property with the same name that you are overriding with GetBatchVectorArray. That property mush have "Hybrid Instanced" checkbox set.
For more info how to setup shaders for BatchRendererGroup, refer to the "Setting up shaders for Hybrid Renderer V1" section in this document:
