Not related, but please note that uuid has changed their declare, this one works for me:

import { v4 as uuidv4 } from 'uuid';

uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'

Hope this helps.

This is not a three.js error, this is a JavaScript error. As the error states Cannot read property 'uuid' of undefined javascript can not read a property of an undefined variable.

Thus, your clipObject is undefined.

You may need to read the JavaScript checking for null vs. undefined and difference between == and ===

It's not the OP's code that is causing this, it seems like its coming from three.js. – pailhead Oct 25 '17 at 18:41
The question was not why the clipObject is undefined :P – GramThanos Oct 25 '17 at 18:46
I jumped to a conclusion too early. I figured that with all these checks the thing that was passed should be properly formatted. You are absolutely correct, the OP copied some code, and passed the wrong thing. – pailhead Oct 25 '17 at 18:58

Removed the three.js tag. – pailhead Oct 25 '17 at 18:59
Why? A problem was w/ threejs example – Alexander Shtang Oct 25 '17 at 19:59
Your question was not. – GramThanos Oct 25 '17 at 20:19

The error was in the following line

var action = mixer.clipAction( animations[ 0 ] ).play();

I used code from example from threejs website and the example was a moving example of a stormtrooper from star wars. But in my example the object is static. So I just removed the line.

To fix error, you need to comment few lines like below (object have`t anim):

const loader = new FBXLoader(); loader.load ( 'files/models/fbx/ContainerBox_05/ContainerBox_05.fbx', function (object) { //mixer = new THREE.AnimationMixer(object); <-- COMMENT THIS

    //const <-- COMMENT THIS
                    
    //action = mixer.clipAction(object.animations[0]); <-- COMMENT THIS
    //action.play(); <-- COMMENT THIS
