problemwith unity 2019 SRP PerobjectLight

i'm writting SRP in Unity 2019.1.2f, and the question is :
how to use unity_LightIndicesOffsetAndCount and unity_PerObjectLightIndices to get lights which most influence the object .

In 2018.3 , I can use unity_LightIndicesOffsetAndCount and unity_4LightIndices0 .
but the new variable doesn't working at 2019.

is there any way to get the result ?

 

Look at CHANGELOG.md of LWRP, section [5.2.0]:

### Changed

- Renamed shader variable `unity_LightIndicesOffsetAndCount` to `unity_PerObjectLightData`.

- Shader variables `unity_4LightIndices0` and `unity_4LightIndices1` are now declared as `unity_PerObjectLightIndices` array.

Rename unity_LightIndicesOffsetAndCount to unity_LightData
Replace float unity_4LightIndices0, unity_4LightIndices1 to real4 unity_LightIndices[2];

And all should works fine (faced same problem first).
