求助！CocosCreator3.8.6 通过代码创建固定关节FixedJoint2D创建问题

[langezi]

使用编辑器为两个body添加固定关节

效果正常：

但是我通过代码创建

    const nodeA = new Node('A')
    nodeA.setParent(this.node)
    nodeA.position = new Vec3(-200, 0, 0)
    nodeA.addComponent(Sprite).spriteFrame = res
    nodeA.getComponent(Sprite).color = Color.RED
    nodeA.getComponent(UITransform).setContentSize(100, 100)
    nodeA.addComponent(RigidBody2D).type = ERigidBody2DType.Dynamic
    nodeA.addComponent(BoxCollider2D).size = new Size(100, 100)

    const nodeB = new Node('B')
    nodeB.setParent(this.node)
    nodeB.position = new Vec3(200, 0, 0)
    nodeB.addComponent(Sprite).spriteFrame = res
    nodeB.getComponent(Sprite).color = Color.GREEN
    nodeB.getComponent(UITransform).setContentSize(100, 100)
    nodeB.addComponent(RigidBody2D).type = ERigidBody2DType.Dynamic
    nodeB.addComponent(BoxCollider2D).size = new Size(100, 100)

    const fixedJoint = nodeA.addComponent(FixedJoint2D)
    fixedJoint.connectedBody = nodeB.getComponent(RigidBody2D)
    fixedJoint.anchor = new Vec2(200, 0)
    fixedJoint.connectedAnchor = new Vec2(-200, 0)

效果就不对，关节节点会被连接到屏幕左下角，nodeB.getComponent(RigidBody2D)打印了，不为空，延迟添加关节也一样！有知道为什么的吗？
