我使用数字海洋空间，并使用aws-sdk上传/删除文件。我已经有这个代码运行了一段时间，但从大约2周前它抛出一个错误。

const listResponse = await this.getDirectoryListing(directory, prefix)
const files = listResponse.Contents ? listResponse.Contents!.map((item) => item.Key!) : []

if (files.length > 0) {
  await this.s3.delete({
    bucket: this.config.env.S3_PUBLIC_BUCKET,
    keys: files,
  })
  this.logger.debug('Old files deleted', { files })
}

抛出的错误是

"type": "S3ServiceException",
"message": "UnknownError",
"stack":
   XAmzContentSHA256Mismatch: UnknownError

s3.delete方法如下所示

async delete(options: IS3Delete): Promise<DeleteObjectsCommandOutput> {
    const deleteObjectsCommand = {
      Bucket: options.bucket,
      Delete: {
        Objects: options.keys.map((item) => ({ Key: item })),
      },
    }

    return this.client.send(new DeleteObjectsCommand(deleteObjectsCommand))
  }
