npx webpack Unexpected token : - node.js

Question

I am trying to use Webpack for the first time with Node and Babel (this is my first time using Babel as well) on Windows 10. I think I have everything configured properly, but it's giving me a cryptic error:
The same thing happens if I do npx webpack --exec bable-node.
In everything I've read about this, it gives a line number. I'm not sure what's the issue.
I have all of the files I thought were related to Node in a folder called "node", and all the other files in a folder called "src". I don't know if this is causing the issue. Here is the folder structure:
/node
/config
/node_modules
.babelrc
master-updated.sh
package-lock.json
package.json
server2.js
webpack.config.js
/src
/model (this is has a bunch of js files, but I removed the references to them for now)
/public
/html
/srcipts
/stylesheets
/css
/scss
/vue
.gitignore
master-updated.sh is a shell script for responding to a GitHub webhook.
Here is the beginning of server2.js:
'use strict';
process.env.NODE_CONFIG_DIR = './node/config';
const config = require('config'),
babel = require('babel-core'),
ejs = require('ejs'),
util = require('util'),
express = require('express'),
bodyParser = require('body-parser'),
cors = require('cors'),
moment = require('moment'),
plaid = require('plaid'),
mariadb = require('mariadb'),
fs = require('fs'),
http = require('http'),
https = require('https'),
session = require('express-session'),
exec = require('child_process').exec;
const GOOGLE_AUTH_CLIENT_ID = '<REDACTED>';
const { OAuth2Client } = require('google-auth-library');
const googleAuthClient = new OAuth2Client(GOOGLE_AUTH_CLIENT_ID);
const APP_PORT = config.APP_PORT;
Here is my webpack.config.js file:
module.exports = {
target: 'node',
entry: {
app: ['./server2.js']
},
output: {
filename: 'server.js',
path: path.resolve(__dirname, 'test')
},
module: {
loaders: [
test: '/\.js$/',
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ["#babel/preset-env"]
}
]
}
}
Here is .babelrc:
{"presets": ["#babel/preset-env"]}
And here is package.json:

These syntax problems are easily identified if you use an IDE which has syntax highlighting, for example VS Code. All I did was copy your config into a file and load it into VS Code.
You are incorrectly closing the regular expression used for exclude:
exclude: /node_modules\,
You must use a forward slash instead of a back slash:
exclude: /node_modules/
You also need to wrap your loader in an object literal:
loaders: [
{ // <= wrap in object literal
test: '/\.js$/',
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ["#babel/preset-env"]
}
}
]
