Express Graphql如何上载多个文件而不是一个文件

大家好，我有一个用于上传图像的graphql解析器。问题是，我想上传多个图像到我不断得到一个错误。这是我的密码。在graphql服务器上上载多个图像的正确方法是什么

分解器

export const uploadImage = async (_, { files }, context) => {
  await jwtAuthentication.verifyTokenMiddleware(context);
  console.log(file);

  try {
    let fileArr = [];

    for (let i = 0; i < files.length; i++) {
      const stream = createReadStream();
      const pathname = path.join(__dirname, `/public/images/${files[i].filename}`);
      await stream.pipe(fs.createWriteStream(files[i].pathname));
      fileArr.push({ path: `${apiUrl}/images/${files[i].filename}` });
    }

    //save image to document

    return fileArr;
  } catch (error) {
    console.log(error);
    // graphqlError(error);
  }
};

前端查询

export const UPLOAD_IMAGE = gql`
  mutation($files: [Upload]) {
    uploadImage(files: $files)
  }
`;

前端上传功能

  const uploadFiles = async (): Promise<void> => {
    try {
      const response = await GraphqlRequest(auth.token).request(UPLOAD_IMAGE, { files });
      console.log(response);
    } catch (err) {
      console.log(err);
    }
  };

constuploadfiles=async（）：Promise=>{
试一试{
const response=wait GraphqlRequest（auth.token）.request（上传图片，{files}）；
控制台日志（响应）；
}捕捉（错误）{
控制台日志（err）；
}
};

什么错误/哪里？什么错误/哪里？

  const uploadFiles = async (): Promise<void> => {
    try {
      const response = await GraphqlRequest(auth.token).request(UPLOAD_IMAGE, { files });
      console.log(response);
    } catch (err) {
      console.log(err);
    }
  };
