Shader being only pink

I’m trying to follow Brackey’s tutorial on creating simple cartoon water. In that he uses a PBR Graph shader. Through googling I’ve learned to use Universla RP and the lit shader graph, but when I put the shader graph onto my material it just turns pink, not matter what I do with the base color. Fix pls?

Usually when something turns pink like that it means that there is no shader or the shader is not loading in. Simply use a different shader, there are plenty of them on the unity asset store.
