How to apply animation to multiple models in a group?

#1

I want to run animation for several models immediately.
But the mixer takes only one model so I added it in a group

model = new THREE.Mesh(new THREE.BoxGeometry(5,5,5), material);
group.add(model)
model2 = new THREE.Mesh(new THREE.BoxGeometry(3,5,2), material);
group.add(model2)
import { MDDLoader } from './three/examples/jsm/loaders/MDDLoader.js';
const loader = new MDDLoader();
loader.load(url, function ( result ) {
	const morphTargets = result.morphTargets;
	const clip = result.clip;
	material.morphTargets = true
	// set new material
	group.children.forEach(function(item, i) {
		group.children[i].geometry.morphAttributes.position = morphTargets;
	});	
	const geometry = new THREE.BoxGeometry();
	geometry.morphAttributes.position = morphTargets;
	const mesh = new THREE.Mesh( geometry, material );
	scene.add( mesh );
	mixer = new THREE.AnimationMixer( group);
	mixer.clipAction( clip ).play(); // use clip
} );
function animated() {
	const delta = clock.getDelta();
	if ( mixer ) mixer.update( delta );
	renderer.render( scene, camera );
}

I get an error

THREE.PropertyBinding: Trying to update property for track: undefined.morphTargetInfluences but it wasn't found.

Explain to me how to apply the animation to each model and after run it
