Three.js node.applyMatrix4 is not a function

I am currently trying to load a .fbx file using the three.js FBXLoader with this code:

var fbxLoader = new THREE.FBXLoader();
fbxLoader.load('assets/item2.fbx', function (object){
object.position.y = - 100;
scene.add(object);
console.log("Object inserted.");     
fitCameraToObject(camera,object,2,controls);
controls.update();
animate();
},
function ( xhr ) {
    console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
    },
function (err) 
{
    console.error(err);
} 
);

(Lines 122-138)

But it is giving me this error upon loading my page webGLLoader.js:
