我有一个上传图片到Cloudinary的程序。当我在我的程序（localhost）+ Heroku上运行它时，它工作得很好（在过去）。但现在不管用了。
错误是：

• 未知API密钥“12345678910”*

对我来说最令人困惑的部分是，当错误消息打印出“Unknown API Key：12345678910”未知密钥与我的Cloudinary API密钥相同：12345678910.
请帮帮我。谢谢你提前

我的.env文件

CLOUDINARY_NAME = 'dupz*****' 
 CLOUDINARY_API_KEY = '532746917******' 
  CLOUDINARY_API_SECRET = 'WpTLLxyJZlMwjUITP**********'

这是我的server.js文件

const app = require("./app");
const { connectDatabase } = require("./config/database");
const cloudinary = require("cloudinary");
connectDatabase();

cloudinary.config({
  cloud_name: process.env.CLOUDINARY_NAME,
  api_key: process.env.CLOUDINARY_API_KEY,
  api_secret: process.env.CLOUDINARY_API_SECRET,
});

这是我的Post.js文件

const Post = require("../models/Post");
const User = require("../models/User");
const cloudinary = require("cloudinary");
exports.createPost = async (req, res) => {
  try {
    const myCloud = await cloudinary.v2.uploader.upload(req.body.image, {
      folder: "posts",
    });
    const newPostData = {
      caption: req.body.caption,
      image: {
        public_id: myCloud.public_id,
        url: myCloud.secure_url,
      },
      owner: req.user._id,
    };

    const post = await Post.create(newPostData);

    const user = await User.findById(req.user._id);

    user.posts.unshift(post._id);

    await user.save();
    res.status(201).json({
      success: true,
      message: "Post created",
    });
  } catch (error) {
    res.status(500).json({
      success: false,
      message: error.message,
    });
  }
};
