Sequelize Eeager加載錯誤 - 無法弄清楚包括

我正在使用Angular和Nodejs構建的應用程序進行sequelize。我已經構建了一個用戶模型，其中有許多通知作爲發件人，並且有許多通知作爲接收者。通知模型也屬於「用戶」作爲發件人，「belongsTo」用戶爲「接收者」。我的問題是，當我嘗試在通知上實現GET http請求時，我收到Sequelize Eager加載錯誤。我已經註釋掉了include語句以及用戶的通知屬性，並且GET請求起作用。我只是不明白是什麼導致了錯誤。Sequelize Eeager加載錯誤 - 無法弄清楚包括

這是我的模特。

「use strict」;

module.exports = function(sequelize, DataTypes) { 
    var Notification = sequelize.define("Notification", { 
    startAddress: DataTypes.STRING, 
    endAddress: DataTypes.STRING, 
    tripDate: DataTypes.DATE, 
    tripHour: DataTypes.INTEGER, 
    numberOfPassengers: DataTypes.INTEGER, 
    price: { 
     type: DataTypes.INTEGER, 
     defaultValue: -1 
    } 
    }); 
    Notification.associate = function(models) { 
    Notification.belongsTo(models.User, { 
     as: "sender", 
     onDelete: "CASCADE", 
     foreignKey: "senderId" 
    }); 
    Notification.belongsTo(models.User, { 
     as: "receiver", 
     onDelete: "CASCADE", 
     foreignKey: "receiverId" 
    }); 
    }; 
    return Notification; 
}; 



"use strict"; 

module.exports = function(sequelize, DataTypes) { 
    var User = sequelize.define("User", { 
    email: DataTypes.STRING, 
    password: DataTypes.STRING, 
    profileImgUrl: DataTypes.STRING, 
    fName: DataTypes.STRING, 
    lName: DataTypes.STRING, 
    yearOfBirth: DataTypes.INTEGER, 
    gender: DataTypes.STRING, 
    ratings: { 
     type: DataTypes.ARRAY(DataTypes.INTEGER), 
     defaultValue: [5] 
    }, 
    createdAt: { 
     type: DataTypes.DATE, 
     defaultValue: sequelize.literal('NOW()') 
    }, 
    updatedAt: { 
     type: DataTypes.DATE, 
     defaultValue: sequelize.literal('NOW()') 
    } 
    }); 
    User.associate = function(models) { 
    User.hasMany(models.RideRequest, { 
     onDelete: "CASCADE", 
     foreignKey: "riderId" 
    }); 
    User.hasMany(models.DriveRequest, { 
     onDelete: "CASCADE", 
     foreignKey: "driverId" 
    }); 
    User.hasMany(models.Notification, { 
     as: 'sender', 
     onDelete: "CASCADE", 
     foreignKey: "senderId" 
    }); 
    User.hasMany(models.Notification, { 
     as: 'receiver', 
     onDelete: "CASCADE", 
     foreignKey: "receiverId" 
    }); 
    }; 
    return User; 
};

這裏是我的通知控制器，它適用於通知路由邏輯。

list: function list(req,res) { 
    var decoded = jwt.decode(req.query.token); 
    return model.User.findOne({ 
     where: {id: decoded.user.id}, 
     include: [{ 
     model: model.Notification 
     }] 
    }).then(function (user) { 
     let ratingAv; 
     for (let rating of user.ratings) { 
      ratingAv = (user.ratings.length/(rating += rating)*10); 
     } 
     console.log(ratingAv + ' RATINGSSSS'); 
     let resObj = Object.assign({}, { 
      id: user.id, 
      profileImgUrl: user.profileImgUrl, 
      fName: user.fName, 
      lName: user.lName, 
      yearOfBirth: user.yearOfBirth, 
      gender: user.gender, 
      ratings: ratingAv, 
      notifications: user.Notifications.map(function(notification) { 
      return Object.assign({}, { 
       id: notification.id, 
       startAddress: notification.startAddress, 
       endAddress: notification.endAddress, 
       tripDate: notification.tripDate, 
       tripHour: notification.tripHour, 
       numberOfPassengers: notification.numberOfPassengers, 
       price: notification.price, 
       senderId: notification.senderId, 
       receiverId: notification.receiverId 
      }); 
      }) 
     }); 
     return res.status(201).json({ 
     message: 'Notifications retrieved successfully', 
     obj: resObj 
     }); 
    }).catch(function (err) { 
     return res.status(400).json({ 
     title: 'There was an error retrieving notifications', 
     error: err 
     }); 
    }); 
    },

如果我甚至能以某種方式得到一個更好的錯誤，我可以弄明白。這個錯誤是非常普遍的，並且不能幫助我理解可能拼寫錯誤或放錯位置等問題。任何人都可以找出問題所在？
