const mongoose = require('mongoose');

const { Schema } = mongoose;

const VacancySchema = new Schema(
    {
        parameters: []
    },
    { timestamps: true },
    { strict: false }
);
      
module.exports = mongoose.model('Vacancy', VacancySchema);

回答如下：

您的Mongoose模式语法错误。我更正为；

const { Schema, model } = require('mongoose');

const VacancySchema = new Schema({
  parameters: [],
  timestamps: true,
  strict: false
});

const Vacancy = model('Vacancy', VacancySchema);

module.exports = Vacancy;
