【已解决】请问下uploader上传失败是什么原因

更新hbuilder后解决了，醉了，希望越做越好
直接贴代码吧，麻烦帮忙看下，十分感谢

//修改头像,原生模式actionsheet  
document.getElementById("picture").addEventListener('tap', function() {  
    plus.nativeUI.actionSheet({  
        cancel: "取消",  
        buttons: [{  
            title: "拍照"

        switch(index) { //case 0: 取消  
            case 1:  
                getImage(); //拍照  
                break;  
            case 2:  
                appendByGallery(); //相册
