nodejs中的流内存泄漏

Question

我正在使用nodejs后端，我需要获取用户正在上传的文件流列表的文件类型。每当我运行getStreamFileTypes函数时，结果都是不正确的，我可能会得到图像的视频文件类型，反之亦然，并在控制台上显示以下错误：

(node:11868) MaxListnersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added. Use emitter.setMaxListeners() to increase limit

该如何解决？这是代码：

const getStreamFileTypes = async (streams) => {
  try {
    // get a list of detector promises
    const typePromises = streams.map(stream => {
      // pipe the stream content to detector
      // to emit file type
      miss.pipe(stream, detector, err => {
        if(err) {
          console.log('an error occured');
          throw err;
        }
      });
      // stream.pipe(detector).resume();
      // return dector filetypepromise that resolves
      // to the file type of the stream
      return detector.fileTypePromise()
        .then(filetype => {
          return { ...filetype, stream };
        })
        .catch(error => {
          throw UnknownError;
        });
    });
    // wait for all stream's filetypes to be detected
    const fileTypes = await Promise.all(typePromises);
    return fileTypes;
  } catch(error) {
    console.log('error occured while getting stream types ', error);
    throw error;
  }
}
