Obi Fluid Renderer not working on URP

[CosmosST]

Hello,

I can't get the Obi Fluid Renderer working on URP. The Obi Particles render fine. 

I have set the Obi Fluid Renderer feature and the script. 

When I check the shaders I see the following errors. Any idea ?  ( OSX , Sonoma )

I don't see any console errors.

thank you.
