I created a shadermaterial material, and this error will appear when I use it.
This is the material I created
var phongShader = THREE.ShaderLib['phong'];
var uniforms = THREE.UniformsUtils.merge([phongShader.uniforms, {
uTime: { type: 'f', value: 0 }
}]);
uniforms.diffuse = 0x444444;
uniforms.specular = 0xcccccc;
var vertexShader = [
