Question about LWRP in 5.0

Unity version 2019.2.11

Exactly the same issue here. However, I was able to attach the rendering feature by editing the ObiFluidRendererFeature.cs file. 

Specifically, I commented the compiler directive #if UNITY_2019_2_OR_NEWER && SRP_LIGHTWEIGHT from the top of the script along with the #endif at the bottom. Looks like it was causing some kind of conflict.
