[LayaAir 2.0]layabox加载fairygui发布的二进制文件报错

用的是layabox2.6.0  在微信小游戏里面可以正常加载，vivo小游戏加载不了，路径没问题，麻烦看下
 
加载代码

            { url:"res/Bag.json", type:Laya.Loader.BUFFER} 
            ], Laya.Handler.create(this, this.onLoaded));
 
Laya.core.js   调试log

resInfo.offAll();
this._infoPool.push(resInfo);
this._statInfo.loaded++;
