I have run it successfully,but why i just have the direction light effect directly?

i notice these two error in fragment shader. its a compile problem maybe,but i never change the shader. how can i fix it,i consider that these two error cause that i only have the direction light effect!

I expect that these Invalid Operation errors are due to the shader having compilation that error.

The error is referring to ´RGBA8´ in this line

That line is perfectly valid GLSL (and it compiles just fine on my PC), so I'm not sure why you are getting that error.
You could try writing the rgba8 in lowercase, or removing the layout qualifier entirely. Not sure... 😅

I presume you are using OpenGL 4.5?
