Problem with the vegetation of the terrain sample asset pack and the shader graphs

Hello, I'm here for someone to solve this problem for me, the thing is that in the last update of the terrain sample asset pack they added vegetation and the thing is that the material is by default as: shader graph/terraingrass but when I see them I see that it's in pink although they already have the texture, their normal maps and the masks but even so the texture of the model is in pink, I have tried to find out how to fix it but I have not had any luck... Does anyone know how to fix it, I would greatly appreciate it ^^

 

Hot pink is usually a missing or misconfigured material or texture, or perhaps unsupported shader feature.

Beyond that I cannot comment as I am an English-only reader on this English forum.

 

I'm sorry, I had also written this in unity answers and since it had the automatic translator activated, it was copied translated, but I have already changed it xd
