Mongodb TypeError: vehicle.save is not a function - mongodb

Question

When I perform a delete request, it returns an error stating that save is not a function
const Vehicle = require('../models/vehicle');
router.delete('/:id', async (req, res) => {
console.log('id: ', req.params.id);
const vehicle = await Vehicle.deleteOne({_id: req.params.id});
try {
vehicle.save();
res.send('ok');
} catch (error) {
console.log('err: ', error);
res.send(error);
}
});
vehicle's schema
const mongoose = require('mongoose');
const vehicle = new mongoose.Schema({
AID: {
type: Number,
required: true
},
OwnerName: {
type: String,
required: true
},
OwnerNIC: {
type: String,
required: true,
},
PhoneNo: {
type: String,
required: true
},
VehicleName: {
type: String,
required: true
},
EngineNo: {
type: String,
required: true
},
ChasisNo: {
type: String,
required: true
},
NoPlate: {
type: String,
required: true
},
RegFees: {
type: Number,
required: true
}
});
module.exports = mongoose.model('Vehicle', vehicle);

Answer 1

I can see some mistakes in your code.
Incorrectly wrapping the await with the try-catch block.
Irrelevant use of the mongoose save(). You don't need to use the save() method when performing a delete request.
Your code should be changed like this:
const Vehicle = require('../models/vehicle');
router.delete('/:id', async (req, res) => {
console.log('id: ', req.params.id);
try {
await Vehicle.deleteOne({_id: req.params.id});
res.send('Vehicle deleted.');
} catch (error) {
console.log('err: ', error);
res.send(error);
}
});

const Vehicle = require('../models/vehicle');
router.delete('/:id', async (req, res) => {
console.log('id: ', req.params.id);
await Vehicle.deleteOne({_id: req.params.id}).then((result) => {
console.log('Result: ', result);
if (result.n > 0) {
res.status(200).json({ message: "Vehicle Deleted" });
} else {
res.status(401).json({ message: "Error to delete " });
}
}).catch((error) => {
res.status(500).json({ message: "Not Delete" });
});
});
