Steps to reproduce

Steps to reproduce:

1 - create a prefab with sp.Skeleton component attached 2 - set a 0 frame animation on the skeleton component on the prefab to play automatically when instantiated 3 - attach a script that will set a listener via skeleton.setCompleteListener in onLoad() function and access the trackEntry.animation.name property 3 - instantiate the prefab and set parent to add to scene 4 - observe the error

onLoad(): void {
        this.skeleton.setCompleteListener((data) => {
            switch (data.animation.name) { // will cause the error
                case 'impact':
                    this.setIdle();
                    break;
                case 'match':
                    this._matchResolve();
                    this.setIdle();
                    break;
            }
        });
    }

Please have a try: 1.switch spine version in project setting. 2.close project, delete library and temp. 3.open the project again.

@Arenooo @finscn @tangkaikk Synchronized the official code， SkeletonBinary It is necessary to check the resources for any slots that lack attachments.

这个 代码我合过来了. 但是感觉和现在的差异很大, 不知道里面是不是有 cocos 不需要的代码.

另外, 还是建议合并一下我这个 PR #19041 . 我是合并这个之后 问题就解决了. 不合并这个 有点类似于无限嵌套调用.
