问云开发中的云存储上传图片BUG？

每次for循环调用该函数，就莫名其妙结束，也没有相关日志，哪位大神遇到过？

async function uploadImg(item) {

let dir = getFileDir();

let cloudPath = dir + createFileName(item.imgUrl);

console.log(TAG, "#uploadImg#cloudPath=", cloudPath, ",uploadImg=", item.imgUrl);

try {

let rs = await app.uploadFile({

cloudPath,

fileContent: request({

url: item.imgUrl

})

})

} catch (e) {

console.log(TAG, "#uploadImg,error", e);

return null;

}

}
