How can I get this DELETE route to work in my products.js route?

I'm having a problem getting my delete route working for removing a single product by grabbing it's _id (5e335c57bd37eb1dd4d99b1f) in Mongoose. I assumed that simply copying the update route and changing it around a bit would work. All the other routes work fine in Postman.

products.js

const express = require("express"),
router = express.Router(),
Product = require("../models/product.model");

// Product list route
router.get("/", function(req, res) {
    Product.find().then(products => {
        res.status(200).json(products);
    }).catch(err => {
        res.status(400).send(`Recieving products failed. Error details: ${err.message}`);
    });
})

// Product details route
router.get("/:product_id", function(req, res) {
    Product.findById(req.params.product_id).then(product => {
        res.status(200).json(product);
    }).catch(err => {
        res.status(400).send(`Recieving product details failed. Error details: ${err.message}`);
    });
})

// Product create logic route
router.post("/add", function(req, res) {
    let product = new Product(req.body);
    product.save().then(product => {
        res.status(200).json({"product": `Product added successfully. Created product details: ${product}`});
    }).catch(err => {
        res.status(400).send(`Adding new product failed. Error details: ${err.message}`);
    });
})

// Product update route
router.put("/:product_id", function(req, res) {
    Product.findById(req.params.product_id).then(product => {
        product.name = req.body.name;
        product.description = req.body.description;
        product.price = req.body.price;
        product.stock = req.body.stock;

        product.save().then(product => {
            res.status(200).json(`Product updated! Updated product details: ${product}`);
        }).catch(err => {
            res.status(400).send(`Update not possible. Error details: ${err.message}`);
        });
    }).catch(err => {
        res.status(404).send(`Product not found. Error details: ${err.message}`);
    });
})

// Product destroy route (NOT WORKING)
router.delete("/:product_id", function(req, res) {
    Product.find(req.params.product_id).then(product => {
        product.remove().then(product => {
            res.status(200).json(`Product deleted! Deleted product details: ${product}`);
        }).catch(err => {
            res.status(400).send(`Delete not possible. Error details: ${err.message}`);
        });
    }).catch(err => {
        res.status(404).send(`Product not found. Error details: ${err.message}`);
    });
})

module.exports = router;

Error in Postman:

<!DOCTYPE html>
<html lang="en">

<head>
	<meta charset="utf-8">
	<title>Error</title>
</head>

<body>
	<pre>Cannot DELETE /products/5e335c57bd37eb1dd4d99b1f</pre>
</body>

</html>

Thank you
