Unable to retrieve the data using ID from MongoDB using Express - node.js

Question

I have created a rest API using NodeJS, Express, and MongoDB. I can successfully create data and view them in the database using MongoDB Compass but can't get single data using Id generated. Whenever I try it gives me a 404 error.
Here is my code:
bootcamps.js (controller)
const Bootcamp = require('../models/Bootcamp')
exports.getBootcamps = async (req, res, next) =>
{
try {
const bootcamps = await Bootcamp.find()
res.status(200).json({success: true, count: bootcamps.length, data: bootcamps})
} catch (error) {
res.status(400).json({success: false})
}
}
exports.getBootcamp = async (req, res, next) =>
{
try {
const bootcamp = await Bootcamp.findById({_id: req.params.id})
if (!bootcamp)
{
return res.status(400).json({success: false})
}
res.status(200).json({success: true, data: bootcamp})
} catch (error) {
res.status(400).json({success: false})
}
}
exports.createBootcamps = async (req, res, next) =>
{
try
{
const bootcamp = await Bootcamp.create(req.body)
res.status(201).json({
success: true,
data: bootcamp,
msg: 'Bootcamp created'
})
} catch (error)
{
console.log(error)
res.status(400).json({success: false})
}
}
exports.updateBootcamp = async (req, res, next) =>
{
try {
const bootcamp = await Bootcamp.findByIdAndUpdate(req.params.id, req.body, {
new: true,
runValidators: true
});
if (!bootcamp)
{
return res.statuc(400).json({success: false})
}
res.status(200).json({ success: true, data: bootcamp })
} catch (error) {
return res.statuc(400).json({success: false})
}
}
exports.deleteBootcamp = async (req, res, next) =>
{
try {
const bootcamp = await Bootcamp.findByIdAndDelete(req.params.id);
if (!bootcamp)
{
return res.statuc(400).json({success: false})
}
res.status(200).json({ success: true, data: {} })
} catch (error) {
return res.statuc(400).json({success: false})
}
}

process.on(`unhandledRejection`, (err, promise) =>

server.close(() => process.exit(1))
})

Found the error!
I forgot to add the '/' on the single route
Before:
router.route(':id').put(updateBootcamp).delete(deleteBootcamp).get(getBootcamp)
After:
router.route('/:id').put(updateBootcamp).delete(deleteBootcamp).get(getBootcamp)
Surprisingly the console and postman result didn't complain and point that out!
