How to use TWEEN to animate the camera's position

function moveCameraTo(position, duration) {
           var tween =  new TWEEN.Tween( camera.position )
                .to( position, duration )
                .easing(TWEEN.Easing.Linear.None)
                .onUpdate(function () {
                    camera.position = new THREE.Vector3().copy(position)
                    camera.lookAt({x:0,y:0,z:0})
                })
                .onComplete(function () {
                    camera.lookAt({x:0,y:0,z:0})
                })
                .start()
        }

I use this method to move the camera to a specific position, and it moves the camera correctly at the beginning. Then the TrackballControls does not work, and there is an error in the console.
