所有其他路由都在工作，除了它显示"internal server error!"的 getEmployees

Question

我的所有其他路由都运行良好，但当我尝试从数据库中提取员工时，它不起作用，我尝试了不同的方法来提取我的员工，即在app.js中使用app.get方法，它起作用了，但当我们尝试将它与控制器和路由一起使用时，它甚至没有到达路由！请帮忙！谢谢！

app.js

const express = require('express')
const app = express();
const appUserRoute = require('./routes/appuserRoute')
const employeeRoute = require('./routes/employeeRoute')
require('./db/mongoose')
app.use(express.json())

if(process.env.NODE_ENV!=="production"){
app.use(morgan('dev'))
}
app.use('/appusers',appUserRoute)

app.use('/appusers/employees',employeeRoute)

//start server
app.listen(PORT,
console.log(`Server running in ${process.env.NODE_ENV } mode on port ${PORT}`.green)
)

employeeRoute.js

const express = require('express')
const router = express.Router();
const {getEmployees, getEmployee, createEmployee, updateEmployee, deleteEmployee } = require('../controllers/employeeController')
router
.route('/')
.get(getEmployees)
.post(createEmployee)
router
.route('/:id')
.get(getEmployee)
.patch(updateEmployee)
.delete(deleteEmployee)

module.exports = router

employeeController.js

const Employee = require('../Models/employee')
exports.getEmployees = async (req, res) => {
try {
const employees = await Employee.find({})
if(!employees){
res.status(404).json({
message:'Not Data Found!'
})
}
res.status(200).json({
message:'Data Found!',
data:employees
})
} catch (e) {
res.status(500).send()
}
}

mongoose.js

const mongoose = require('mongoose')
mongoose.connect('mongodb://127.0.0.1:27017/MagicInventory-api', {
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
useUnifiedTopology: true
}).then(() => console.log("Connected".green))
.catch(err => console.log(err.red));

员工模型

const mongoose = require('mongoose');
var validator = require('validator');
const employeeSchema = new mongoose.Schema({
firstName: {
type: String,
required: [true, 'please specify First Name'],
trim: true,
maxlength: [20, 'FirstName cannot be more than 20 characters!']
},
lastName: {
type: String,
trim: true,
// maxlength: [20, 'lastName cannot be more than 20 characters!']
},
email: {
type: String,
trim: true,
lowercase: true,
// unique: true,
// required: [true,'Email address is required'],
// validate: {
//     validator: validator.isEmail,
//     message: 'invalid email',
// }
},
maritalStatus: {
type: String,
// required:[true, 'Choose the Gender']
},
dateOfBirth: {
type: Date,
// required: [true, 'Date of Birth is required!']
},
profile: {
type: String,
lowercase: true
},
contactDetails: {
adressLine1: {
type: String
},
adressLine2: {
type: String
},
city: {
type: String
},
state: {
type: String
},
zipCode: {
type: Number
},
country: {
type: String
},
contact: {
type: Number,
match: [
/^(?([0-9]{3}))?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/,
'Phone number is not valid!'
]
},
},
bankDetails:{
bankName:{
type:String,
},
accountNumber:{
type:Number
},
accountName:{
type:String
},
ifscCode:{
type:String
}
},
dateOfJoining:{
type: Date,
},
createdAt: {
type: Date,
default: Date.now
},

});

module.exports = mongoose.model('Employee', employeeSchema)

问题解决了！我在写路线时犯了一个错误！实际路线应该是：-app.use('/employee'，employeeRoute(；
