Node.js/Express post request unsuccessful - node.js

Question

I have a simple CRUD app in Node.js/Express. It's an order intake form to post data to a MongoDB collection.
I cannot for the life of me see why this POST (CREATE) route is not succeeding. I’ve been troubleshooting this all morning. My other routes run just fine as validated with my console.logs.
Here is my orders route file (/routes/orders.js):
var express = require("express");
var router = express.Router();
var Order = require("../models/order.js");
// Load Keys ===================================================================
const keys = require('../config/keys');
// INDEX ROUTE - show all orders
router.get("/", isLoggedIn, function(req, res){
// Get all orders from DB
Order.find({}, function(err, allOrders){
if(err){
console.log(err);
} else {
res.render("orders", {orders:allOrders});
//Test to see if this returns the number of records in the collection
console.log("There are currently " + allOrders.length + " orders.");
}
});
});
// CREATE ROUTE - add new order to the DB
router.post("/", isLoggedIn, function(req, res){
// get data from form and add to newOrder object
var date = req.body.date;
var territory = req.body.territory;
var principal = req.body.principal;
var customer = req.body.customer;
var representative = req.body.representative;
var amount = req.body.amount;
var newOrder = {date: date, territory: territory, principal: principal, customer: customer, representative: representative, amount: amount};
// Create a new order and save to DB
Order.create(newOrder, function (err, newlyCreated){
if(err){
console.log(err);
} else {
//redirect back to orders page
res.redirect("/");
console.log("New order created (orders route file).");
}
});
});
// NEW ROUTE - show form to create new customer
router.get("/new", isLoggedIn, function(req, res){
res.render("new.ejs");
console.log("This is coming from the order route js file.");
});
This is my new.ejs template file with the form:
<div class="container container-new py-5">
<div class = "row">
<div class="col-lg-12 orders-title">
