This is my first Stack overflow posting.I’m new to the MERN stack and I’m having trouble POSTing raw data to my web application from postman.
The data:

{
    "title": "Situps",
    "load": 0,
    "reps": 50
}

the error I get when i send a POST request is:

{
    "error": "Operation `workouts.insertOne()` buffering timed out after 10000ms"
}

This is the .js file i think may be the culprit:

const express = require('express')
const Workout = require('../models/workoutModel')

const router = express.Router() 

// Get all workouts
router.get('/', (req, res) => {
    res.json({mssg: 'Get all workouts'})
})

// Get single workout
router.get('/:id', (req, res) => {
    res.json({mssg: 'Get a single workout'})
})

// Post a new workout
router.post('/', async (req, res) => {
    const {title, load, reps} = req.body

    try {
        const workout = await Workout.create({title, load, reps})
        res.status(200).json(workout)
    }   catch (error) {
        res.status(400).json({error: error.message})
    }
})

// Delete a workout
router.delete('/:id', (req, res) => {
    res.json({mssg:'Delete a workout'})
})

// Update a workout
router.patch('/:id', (req, res) => {
    res.json({mssg:'Update a workout'})
})

module.exports = router
