Mongoose Alert: Unable to Create Schema Instance

Below is the Schema file that I'm using:

const mongoose = require("mongoose");

const ProblemSchema = new mongoose.Schema(
  {
    slug: {
      type: String,
      required: true,
      unique: true,
    },
    title: {
      type: String,
      required: true,
    },
    desc: { type: String },
    input: { type: String, required: true },
    output: { type: String, required: true },
    constraints: { type: String },
    statement: { type: String, required: true },
    testcase: [
      {
        input: { type: String },
        output: { type: String },
        sample: { type: Boolean },
        explanation: { type: String },
      },
    ],
  },
  { timestamps: true }
);

module.exports = mongoose.model("Problem", ProblemSchema);

Whenever I try to save data with the following code:

const Problem = require("./models/Problem");
const newData = new Problem(data)
await newData.save()

I encounter the error message "Problem is not a constructor." How can I resolve this issue? Appreciate your help in advance.

Answer №1

To bring in your model, use this format.

const Model = require("./your_model_file_path");

Avoid using this method.

const { Model } = require("./your_model_file_path");

No need to destructure during import.
