不知道我在這裏做錯了什麼......我試圖從nodejs上使用knox庫上傳視頻(多部分)從android到AmazonS3時不斷收到此錯誤...我正在使用異步庫以及等待影片完成上傳之前,我調用回調(CB)的下一個功能這裏是我的錯誤:繼續收到函數錯誤不知道爲什麼

下面是代碼:
function setupAndCreateImage (cb) {
if(req.files && req.files.mediaFile) {
console.log("Received file:\n" + JSON.stringify(req.files));
//add p for pics will do v for vids
videoID = "v" + path.basename(req.files.mediaFile.path);
tmp_path = req.files.mediaFile.path;
//targetPathSmall = './public/img/challenges/' + videoID;
//videoConvert = req.files.mediaFile.name;
var video = req.files.mediaFile;
var s3Headers = {
'Content-Type': video.type,
'Content-Length': video.size,
'x-amz-acl': 'public-read'
};
//console.log('stdout:', stdout, targetPathSmall)
s3.putStream(tmp_path, videoID, s3Headers, function(err, s3response){
//handle, respond
if(err) {
console.log(err);
} else {
s3response.resume();
console.log("saved to S3");
//console.log(s3response);
cb(null, videoID);
}
});
} else {
videoID = "";
cb(null, videoID);
}
},
