使用import（）模型时，sequelize无法创建记录

Question

这是一个非常奇怪的问题。 如果我通过Sequelize.import（）定义模型，则Sequelize无法创建记录-返回错误“从字符串转换日期和/或时间时转换失败”。但是，如果我在主模块中使用Sequelize.define（）定义了SAME模型，则它可以完美地工作。作为Sequelize的新手，这让我感到困惑。

这是模型文件中的代码

/* jshint indent: 2 */

module.exports = function(sequelize, DataTypes) {
  return sequelize.define('Sale', {
    SaleID: {
      type: DataTypes.INTEGER,
      allowNull: false,
      autoIncrement: true,
      primaryKey: true
    },
    SaleTypeID: {
      type: DataTypes.INTEGER,
      allowNull: false,
      references: {
        model: 'SaleTypeMaster',
        key: 'SaleTypeID'
      }
    },
    LocationID: {
      type: DataTypes.INTEGER,
      allowNull: false,
      references: {
        model: 'Location',
        key: 'LocationID'
      }
    },
    TillID: {
      type: DataTypes.INTEGER,
      allowNull: false
    },
    SaleStartDateTime: {
      type: DataTypes.DATE,
      allowNull: false
    },
    SystemCashierID: {
      type: DataTypes.INTEGER,
      allowNull: true
    },
    ShiftID: {
      type: DataTypes.INTEGER,
      allowNull: true
    },
    SaleTotalInc: {
      type: DataTypes.DECIMAL,
      allowNull: true
    },
    TaxTotal: {
      type: DataTypes.DECIMAL,
      allowNull: true
    },
    HostCashierName: {
      type: DataTypes.STRING,
      allowNull: true
    },
    HostSaleID: {
      type: DataTypes.STRING,
      allowNull: true
    },
    HostAlternateSaleID: {
      type: DataTypes.STRING,
      allowNull: true
    },
    NavSaleExport: {
      type: DataTypes.INTEGER,
      allowNull: true
    }
  }, {
    tableName: 'Sale',
    timestamps: false
  });
};

这是主模块

const EMCSale = etlDb.import("./etl/Sale");
EMCSale.sync();
/*
const EMCSale = etlDb.define('Sale', {
    SaleID: {
        type: Sequelize.INTEGER,
        allowNull: false,
        autoIncrement: true,
        primaryKey: true
      },
    SaleTypeID: {
        type: Sequelize.INTEGER,
        allowNull: false,
        references: {
            model: 'SaleTypeMaster',
            key: 'SaleTypeID'
        }
    },
    LocationID: {
        type: Sequelize.INTEGER,
        allowNull: false,
        references: {
          model: 'Location',
          key: 'LocationID'
        }
    },
    TillID: {
        type: Sequelize.INTEGER,
        allowNull: false
    },
    SaleStartDateTime:  {
        type: Sequelize.DATE,
        allowNull: false
    },
    SystemCashierID: {
        type: Sequelize.INTEGER,
        allowNull: true
      },
      ShiftID: {
        type: Sequelize.INTEGER,
        allowNull: true
      },
      SaleTotalInc: {
        type: Sequelize.DECIMAL,
        allowNull: true
      },
      TaxTotal: {
        type: Sequelize.DECIMAL,
        allowNull: true
      },
      HostCashierName: {
        type: Sequelize.STRING,
        allowNull: true
      },
      HostSaleID: {
        type: Sequelize.STRING,
        allowNull: true
      },
      HostAlternateSaleID: {
        type: Sequelize.STRING,
        allowNull: true
      },
      NavSaleExport: {
        type: Sequelize.INTEGER,
        allowNull: true
      }
    },    
  {
    tableName: 'SaleX',
    timestamps: false
  });
*/

var newSaleRec = {
    SaleTypeID: 0, 
    LocationID: 100, 
    TillID: 1,
    SaleStartDateTime: "2019-03-15T12:00:00.000"
}   

var User = etlDb.define('user', {
    username: Sequelize.STRING,
    birthday: Sequelize.DATE
  });

  etlDb.sync().then(function() {
    return User.create({
      username: 'janedoe',
      birthday: "2019-03-12T12:00:00.000"
    });
  }).then(function(jane) {
    console.log(jane.get({
      plain: true
    }));
    return EMCSale.create(newSaleRec);


  }).then(function(sale) {
    console.log(sale.get({
        plain: true
      }));

  }).catch(err => {
    console.log("Done with error "+err);

})

这是输出-首先是使用定义时，然后是使用导入时
