Error message encountered: "myData undefined while executing server in Node.js"

const express = require('express');
const app = express();

app.post('/', (req, res) => {
    let newData = new contact(req.body);
    newData.save()
        .then(() => {
            res.send("Data has been successfully saved to the database");
        })
        .catch(() => {
            res.status(400).send("Error: Data was not saved to the database");
        });
});

I am encountering an error which states that newData is not defined.


Answer №1

To avoid the undefined error, make sure to update the scope as shown below:

app.post('/', (req, res) => {
  let myData = new contact(req.body);
  myData.save().then(() => {
    res.send("The data has been successfully saved in the database");
  })
  .catch(() => {
    res.status(400).send("Failed to save data to the database");
  });
});

Make sure to change the scope of myData in your code to prevent any errors.
