Universal Render Pipeline (2019.3.0f3) and pink render errors :(

Hello, I want to use your shader in my project,because is very cool! I will try make another one by myself using your guide, but now I need really hard and just use your project. Problem is that your material with your shader is turns to pink color without any error, I found that maybe main thing that works wrong is line with "LightMode" = "ForwardBase"? Only colors and rendering dont work, but blades of grass still works very well, because i saw them in wireframe mode. Shader works if //comment line with lightmode and in fragment shader comment all except line return col with some value. What I can do to make shader works like in 2018 version of unity?) Thank you very much! for your work!
