Question Shadergraph pink after build

Hi,

When i build with our buildserver (in batch mode) this error occurs:

Code (Boo):

When i build with unity on my pc i still get these errors except the "plantCutHighlight" errors. This is troublesome because this shader is renderer pink. The others shaders we don't use.

I tried to locate the source of this error and it happens when i add this to my shadergraph:

View attachment 479321

It's nothing fancy, i use the same nodes in the same shadergraph without any issues.

The attached zip contains both working and "broken" shader.

Some help is greatly appreciated.

Thanks!
