我正在使用graphql-upload将文件从node.js graphql API上传到s3，

const { createReadStream, mimetype, filename } = file;
                const fileStream = createReadStream();
                const prefix = encodeURIComponent(folder) + '/';
                const uploadParam = {
                    Bucket: bucket,
                    Key: `testing`,
                    Body: fileStream,
                    ContentType: mimetype,
                };
                await s3.send(new PutObjectCommand(uploadParam));

每次我上传，它显示这个错误

NotImplemented: A header you provided implies functionality that is not implemented
  Code: 'NotImplemented',
  Header: 'Transfer-Encoding',

我做错了什么？
