Could you let me know what is wrong here?

<script>
        init();
        animate();

        function init() {
            var scene = new THREE.Scene();
            var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
            var renderer = new THREE.WebGLRenderer({
                alpha: true
            });
            renderer.setSize(window.innerWidth, window.innerHeight);
            renderer.outputEncoding = THREE.sRGBEncoding;
            document.body.appendChild(renderer.domElement);

            window.addEventListener('resize', function() {
                var width = window.innerWidth
                var height = window.innerHeight
                renderer.setSize(width, height);
                camera.aspect = width / height;
                camera.UpdateProjectionMatrix();
            })

            stats = new Stats();
            document.body.appendChild(stats.dom);

            controls = new THREE.OrbitControls(camera, renderer.domElement);

            var AmbientLight = new THREE.AmbientLight(0xFFFFFF, 1);
            scene.add(AmbientLight);

            var pointLight = new THREE.PointLight(0xffffff, 0.7);
            pointLight.position.set(0, 3, 0);
            scene.add(pointLight);

            var light = new THREE.DirectionalLight(0xffffff, 1);
            light.position.set(0, 20, 30);
            light.castShadow = true;
            scene.add(light);

            // envmap
            var path = 'js/';
            var format = '.jpg';
            var envMap = new THREE.CubeTextureLoader().load([
                path + 'posx' + format, path + 'negx' + format,
                path + 'posy' + format, path + 'negy' + format,
                path + 'posz' + format, path + 'negz' + format
            ]);



            var dracoLoader = new DRACOLoader();
            dracoLoader.setDecoderPath('js/');

            var loader = new THREE.GLTFLoader();
            loader.setDRACOLoader(dracoLoader);
            loader.load('js/object.glb', function(gltf) {

                var model = gltf.scene;
                model.position.set(0, 0, 0);
                model.rotation.y = Math.PI / 2;
                model.scale.set(0.05, 0.05, 0.05);
                model.traverse(function(child) {
                    if (child.isMesh) child.material.envMAp = envMap;
                });

                scene.add(model);

            }, undefined, function(error) {

                console.error(error);

            });

            camera.position.z = 10

        }

        function animate() {
            requestAnimationFrame(animate);

            render();
            stats.update();

        }

        function render() {

            if (model !== null) {
                model.rotation.x += 0.01;
                model.rotation.y += 0.01;

                renderer.render(scene, camera);
            }
        }
    </script>

Thank You!
