我在使用nodejs上传cloudinary视频时遇到错误。我得到错误{ message: 'Invalid image file', name: 'Error', http_code: 400 }，即使我上传.mp4文件或视频文件，我仍然得到错误。我尝试与图像配置上传图像，它是成功地得到上传。我正在使用multer库这一点
我尝试上传不同大小的视频和不同的扩展名，我已经过滤文件与mimetype“视频/mp4”，我试图复制和粘贴教程的代码，但仍然没有运气，得到错误，我试图搜索网页和chatgpt，但没有运气。希望好心人和栈溢出的成员帮助我。
谢谢你提前：）
我的multer配置文件：

const multer = require("multer");
    const storage = multer.diskStorage({
    filename: (req, file, cb) => {
    const fileExt = file.originalname.split(".").pop();
    const filename = `${new Date().getTime()}.${fileExt}`;
    cb(null, filename);
    },
    });
    const imageFileFilter = (req, file, cb) => {
    if (!file.mimetype.startsWith("image")) {
    cb("Supports only image files!", false);
    }
    cb(null, true);
    };
    
    const videoFileFilter=(req, file, cb) => {
    // if (!file.mimetype.startsWith("video")) {
    //   cb("Supports only video files!", false);
    // }
      if(file.mimetype!=="video/mp4"){
        cb("Supports only video files!", false);
      }
    
      cb(null, true);
    
    };
    
    exports.uploadImage = multer({ storage, fileFilter:imageFileFilter });
        exports.uploadVideo = multer({ storage, fileFilter:videoFileFilter});
        

my router file :
`router.post('/upload-trailer',uploadVideo.single('trailer'),uploadTrailer);`

my controller file :

`exports.uploadTrailer = async (req, res,next) => {
    const { file } = req;
    console.log(file)
    try{
        if (!file) return sendError(res, "Video file is missing!");
      
        const { secure_url: url, public_id } = await cloudinary.uploader.upload(
          file.path,
          {
            resource_type: "video",
          }
        );
        res.status(201).json({ url, public_id });
    }
    catch(error){
      console.log(error)
        next(error)
    }
  };`
