OSS IOS多图片循环上传只有部分成功

同时选择了多个图片，然后循环上传，结果只有一部分成功，另外的报错如下：
UserInfo={__name=Error, HostId=120.77.166.49, BucketName=product_F793D9FC-8A15-4D51-9F86-5E6D71FD8778.jpg, Message=The specified bucket is not valid., Code=InvalidBucketName,

代码如下：
let ossClient = OSSClient.init(endpoint: self.endPoint, credentialProvider: ossProvider!)

            ossClient.clientConfiguration = conf
            //let queue = OperationQueue()
          //  queue.maxConcurrentOperationCount = self.upload_imageDatas.count
            var index = 0
            for imageData in self.upload_imageDatas{
                
               // let operation = BlockOperation { () -> Void in
                    let put = OSSPutObjectRequest()
                    
                    // required fields
                    put.bucketName = self.bucketName!
                    
                    let fileName = CommonUtil.getUUID()
                    
                    put.objectKey = "product-\(fileName).jpg".lowercased()
                    
                    put.uploadingData = imageData as Data!
                    
                     print("bucket name: " + put.bucketName)
                    let ossTask = ossClient.putObject(put)
                    ossTask.waitUntilFinished()
                    if (!(ossTask.error != nil)) {
                        print("upload success")
                        self.updateAvatarToServer(productId: productId, fileName: fileName)
                    } else {
                        print(ossTask.error!)
                    }
