OBJ model not loading in Three.JS

Question

I'm trying to load obj models, here's code (CoffeeScript)

loader = new THREE.OBJLoader manager 

if loadedModels.diamondRing == null

    loader.load "obj/diamond/ring1.obj", (object) ->

        object.traverse (child) ->
            if child instanceof THREE.Mesh
                child.material = silverMaterial.clone()

        object.position.y = 10
        object.scale.x = object.scale.z = object.scale.y = config.p1.size*0.05

        object.userData.ring = true
        combine.add object 

        loadedModels.diamondRing = combine.clone()


    loader.load "obj/diamond/diamond1.obj", (object) ->

        object.traverse (child) ->
            if child instanceof THREE.Mesh
                child.material = silverMaterial.clone()

        object.position.y = 10
        object.userData.diamond = true
        object.scale.x = object.scale.z = object.scale.y = config.p1.sizeDiamond*0.075

        combine.add object 

But I caught exception:

Uncaught TypeError: Cannot read property 'clone' of undefined obj.js:93

where obj.js - THREE.OBJLoader.

on line 93 placed add_face function:

    function add_face( a, b, c, normals_inds ) {

        if ( normals_inds === undefined ) {

            geometry.faces.push( face3(
                vertices[ parseVertexIndex( a ) ] - 1,
                vertices[ parseVertexIndex( b ) ] - 1,
                vertices[ parseVertexIndex( c ) ] - 1
            ) );

        } else {

            geometry.faces.push( face3(
                vertices[ parseVertexIndex( a ) ] - 1,
                vertices[ parseVertexIndex( b ) ] - 1,
                vertices[ parseVertexIndex( c ) ] - 1,
                [
 -- line 93 -->     normals[ parseNormalIndex( normals_inds[ 0 ] ) ].clone(),
                    normals[ parseNormalIndex( normals_inds[ 1 ] ) ].clone(),
                    normals[ parseNormalIndex( normals_inds[ 2 ] ) ].clone()
                ]
            ) );

        }

    }

I think problem in normals, but i dont know where exactly. Reading model problem happened on last lines, like this:

 f 6802//6802 6803//6803 6804//6804

If in obj model remove affected lines:

In 3d editor model look normal. May be someone faced such problem.

I solved the problem by changing standard obj loader to this https://github.com/maxogden/stl-obj-viewer
