Soy nuevo en aprender desarrollo web usando node.js y express.js. Cuando pruebo mi código en Postman, el servidor falla y me da este error this.$__.validationError = new ValidationError(this) . Estoy creando un servidor back-end conectado a MongoDB y al paquete mongoose.

Rutas

 const express = require('express') const router = express.Router() const { create } = require('./../controllers/courseControllers') const {verifyAdmin, verify} = require('./../auth') router.post('/create', verifyAdmin, async (req, res) => { // console.log(req.body) try{ create(req.body).then(result => res.send(result)) }catch(err){ res.status(500).json(err) } })

Controladores

 const Course = require('../models/Course'); //CREATE A COURSE module.exports.create = async (reqBody) => { const {courseName, description, price} = reqBody let newCourse = new Course({ courseName: courseName, description: description, price: price }) // console.log(newCourse) return await newCourse.save().then((result, err) => result ? result : err) }

Esquema

 const mongoose = require('mongoose'); const courseSchema = new mongoose.Schema({ courseName: { type: String, required: [true, `Course name is required`], unique: true }, description: { type: String, required: [true, `Course description is required`] }, price: { type: Number, required: [true, `Price is required`] }, isOffered: { type: Boolean, default: true }, enrollees: [ { userId: { type: String, required: [true, `userId is required`] }, enrolledOn: { type: Date, default: new Date() } } ] }, {timestamps: true}) module.exports = mongoose.model("Course", courseSchema);
