Shader compiler: internal error compiling shader snippet type=0 platform=0:

Cant find any information about this error. I’m writing a basic flat color shader as part of a tutorial and I’m pretty sure I wrote it out correctly. Any ideas on what I’m doing wrong? I’m on a 2014 macbook pro. TIA!

Here are the errors I get:

Shader compiler: internal error compiling shader snippet type=0 platform=0: 
Shader error in 'Custom/Tutorial/FlatColor - 1': Internal error communicating with the shader compiler process

Here’s my simple flat color shader:

Shader "Custom/Tutorial/FlatColor - 1" {
	Properties {
		_Color ("Color", Color) = (1.0,1.0,1.0,1.0)
	}
	
	SubShader {
		Pass {
			CGPROGRAM
			//pragmas
			#pragma vertex vert
			#pragma fragment frag
			
			//user defined vars
			uniform float4 _Color;
			
			//structs
			struct vertexInput{
				float4 vertex : POSITION;
			}
			
			struct vertexOutput{
				float4 pos : SV_POSITON;
			}
//			
			//vert prog
			vertexOutput vert(vertexInput v){
				vertexOutput o;
				o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
				return o;
			}	
			
			//frag program		
			float4 frag(vertexOutput i) : COLOR
			{
				return _Color;
			}
//			
			ENDCG
		}
	}
	
	
	//fallback "Diffuse"
}

Ahah!
Missing my semicolons at the end of the struct definitions. Problem solved!
