aws-sdk multipart upload error complete mltipart

Question

我试图在节点 js 中将大文件上传到 s3， 所有部分都已上传，但在 MultipartUpload 中，当我尝试合并所有部分时出现错误：InvalidPart: null 这是相关代码：

let partNumber=1;
let numPartsUploaded=0;

readStream.on("data", (chunk)=>{
  const partParams={
    Bucket="myBucketName",
    Key="name",
    PartNumber:partNumber,
    UploadId:uploadId,
    Body:chunk
  };
  s3.uploadPart(partParams, (err,data)=>{
  if(err){
    console.log("Error upload part", err)
    return;}
  consol.log(`part ${partNumber} uploaded successfully`)
  parts.push({ETag:data.ETag,PartNumber:partNumber});
  partNumber++;
  numPartsUploaded++;
  if(numPartsUploaded===Math.ceil(readStream.bytesRead/partSize)){
    s3.completeMultipartUpload({
      Bucket="myBucketName",
      Key="name",
      UploadId:uploadId,
      MultipartUpload:{Parts:parts},},(err,data)=>{
        if(err){
          consol.log("error: ",err) 
          return;}
        consol.log("file uploaded successfully")
      });}});});

我也没有看到 s3 中的部分，但是也许在上传完成之前我看不到它？

感谢任何回答

我记录了零件数组，没有 null 看起来不错
