What happened?

I have some code that uses vaUV2 to get the base Minecraft lighting engine working (I am making a boilerplate shader), but when I import vaUV2 into my vertex shaders it says "Iris encountered an issue trying to load the shader; please report this to Iris developers" and when I copy info it says to look at the log.
