不同设备出现JsonWebToken过期/格式错误，致MongoDB/React项目无限循环

删除用户模型/控制器中必填的"name"字段后，我的MongoDB/React项目本地启动后立刻陷入无限刷新循环，但Heroku线上版本仍能正常运行，这个问题已经卡了几周。

已尝试的解决方法 #

• 重置到最后一个可正常运行的提交版本
• 在未修改代码的其他设备上测试
• 删除并重新安装前后端目录下的node_modules和package-lock.json文件
• 创建全新数据库并更新MONGO_URI环境变量

JsonWebToken: JWT Expired

相关代码文件 #

authMiddleware.js #

const jwt = require("jsonwebtoken");
const asyncHandler = require("express-async-handler");
const User = require("../model/userModel");

const protect = asyncHandler(async(req, res, next) => {
    let token;

    if(req.headers.authorization && req.headers.authorization.startsWith("Bearer")) {
        try {
            token = req.headers.authorization.split(" ")[1]

            const decoded = jwt.verify(token, process.env.JWT_SECRET)
            req.user = await User.findById(decoded.id).select("-password")

            next()
        } catch (error) {
            console.log(error);
            res.status(401)
            throw new Error("Not authorized");
        }
    }

    if (!token) {
        res.status(401)
        throw new Error("Not authorized, no token")
    }
});

module.exports = { protect };

User Model #

const mongoose = require("mongoose");

const userSchema = mongoose.Schema({
    email: {
        type: String,
        required: [true, "Please add an email"],
        unique: true
    },
    password: {
        type: String,
        required: [true, "Please add a password"]
    }
}, {
    timestamps: true
})


module.exports = mongoose.model("User", userSchema)

补充：Redux开发者工具错误信息 #

我已经删除了用户模型和认证相关的所有"name"内容，但仍出现以下错误：

auth:{
   user: {
      message(pin):"name is not defined"
      stack(pin):"ReferenceError: name is not defined at 
      /home/erickbravo/ebravo/Practice/parts- 
      house3/backend/controllers/userController.js:28:5"
     }
}
