Cloudinary Missing需要参数 - public_id错误

Question

以下是我的代码，当我发送删除请求时，我一直在标题中收到错误。我只在下面包含了创建和删除路由。我不熟悉cloudinary，如果有人可以解释我的错误，我将不胜感激。我很高兴终于有一个部分工作的上传系统，但我真的想把它全部搞定并且完善，只是让删除工作会很棒。

var express = require("express");
var router  = express.Router();
var Post = require("../models/post");
var middleware = require("../middleware");

// --------multer config
var multer = require('multer');
var storage = multer.diskStorage({
  filename: function(req, file, callback) {
    callback(null, Date.now() + file.originalname);
  }
});
var imageFilter = function (req, file, cb) {
    // accept image files only
    if (!file.originalname.match(/\.(jpg|jpeg|png|gif)$/i)) {
        return cb(new Error('Only image files are allowed!'), false);
    }
    cb(null, true);
};
var upload = multer({ storage: storage, fileFilter: imageFilter})
var apisecret ="*removed for safety*";
var cloudinary = require('cloudinary');
cloudinary.config({ 
  cloud_name: 'dkjjx5pgg', 
  api_key: *removed for safety*, 
  api_secret: apisecret
});

// -------multer end 




//CREATE - add new post to DB
router.post("/", middleware.isLoggedIn && middleware.isAdmin, upload.single('image'), function(req, res){
    // get data from form and add to posts array
    cloudinary.v2.uploader.upload(req.file.path, function(err, result) {
      if(err) {
        req.flash('error', err.message);
        return res.redirect('back');
      }
      // add cloudinary url for the image to the post object under image property
      req.body.post.image = result.secure_url;
      // add image's public_id to post object
      req.body.post.imageId = result.public_id;
      // add author to post
      req.body.post.author = {
        id: req.user._id,
        username: req.user.username
      }
      Post.create(req.body.post, function(err, post) {
        if (err) {
          req.flash('error', err.message);
          return res.redirect('back');
        }
        res.redirect("/posts");
      });
    });
});

// DESTROY posts ROUTE
router.delete('/:id', function(req, res) {
  Post.findById(req.params.id, async function(err, post) {
    if(err) {
      req.flash("error", err.message);
      return res.redirect("/posts");
    }
    try {
        await cloudinary.v2.uploader.destroy(post.imageId);
        post.remove();
        req.flash('success', 'Post deleted successfully!');
        res.redirect('/posts');
    } catch(err) {
        if(err) {
          req.flash("error", err.message);
          return res.redirect("/posts");
        }
    }
  });
});


module.exports = router;
