NodeJS: Heroku deployment internal server, EJS template "not a function" error - javascript

I have a NodeJS app, with EJS as the templating engine, and when I deploy to Heroku I'm getting an internal server error. Here are the logs:

entries.at is pulling from a MongoDB database with Mongoose, it's populating data from the db.
I've tried to set the views directory to be relative and absolute (per an SO question/answer), and that didn't work.
Here's what entries references:
homepageController.js:
// get home page ('index');
const Entry = require("../models/posts");
exports.homepage = async(req,res) => {
let entries = await Entry.find({})
await res.render('index', {
title: 'Food Blog | Tyler Duke Dev',
entries
});
};
the model:
const mongoose = require('mongoose');
const entrySchema = new mongoose.Schema({
category: {
type: String,
required: true
},
title: {
type: String,
required: true
},
desc: {
type: String,
required: true
},
author: {
type: String,
required: true
},
dateCreated: {
type: Date,
required: true
},
readTime: {
type: String,
required: true
}
})
const Entry = mongoose.model('Entry', entrySchema);
module.exports = Entry;

Node.js application error when deploying on heroku

My program crashes. the website does not even load for a second. It loads until the program crashes. I tried changing the JSON and the Procfile but nothing seems to work. I tried restarting Heroku and I have no env variables, but nothing worked though.
Here are the Heroku logs:

Heroku Error. Cannot find module 'Mongoose'

For some odd reason (i have been deployed on Heroku for around 1.5 years) my instance decided to throw a weird error regarding not finding 'mongoose' after attempting to deploy again. Everything works on my local server and my .gitignore file ignores Node Modules. This is a React.js app with Expressjs and Mongoose.
Here is my Package.json:

}
}
Here is my webpack.config.js
const path = require('path');
const SRC_DIR = path.join(__dirname, '/client/src');
const DIST_DIR = path.join(__dirname, '/client/dist');
module.exports = {
entry: `${SRC_DIR}/index.js`,
output: {
filename: 'bundle.js',
path: DIST_DIR,
},
module: {

loader: 'babel-loader',
query: {
presets: [

'#babel/preset-react'
],
},
},
],
},
};
Here is my Database folder:
require('dotenv').config();
const mongoose = require('mongoose');
// dev
// process.env.mongourl
mongoose.connect(process.env.mongourl)
.catch(err => console.log('Mongo connection error', err));
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', () => {
console.log('MongoDB has connected');
});
// schemas
const comingSoonSchema = ({
address: String,
desc: String,
sqft: Number,
bed: String,
bath: String,
photoLink: String,
agent: String,
price: String,
year: Number,
eta: String,
premarket: String,
status: String,
timeStamp: { type: Date, default: Date.now },
})
// models
const ComingSoon = mongoose.model('ComingSoon', comingSoonSchema);
function save(e) {
console.log(e, "SAVE FUNC");
const obj = new ComingSoon({
address: e.address,
desc: e.desc,
sqft: e.sqft,
bed: e.bed,
bath: e.bath,
photoLink: e.photoLink,
agent: e.agent,
price: e.price,
year: e.year,

premarket: e.premarket
})
obj.save();
console.log("Data saved to MongoDB Database");
}
const funcs = {
save, ComingSoon,
};
module.exports = funcs;
And lastly here is the persisting error:

The error is most likely coming from the fact that you have mongoose in your "devDependencies". Try moving it to your "dependencies", then running npm install. You may run into the same issue with express and a few others under "devDependencies". Hope this helps.

It does not make any sense, but if mongoose is both in dev dependencies and in dependencies, heroku goes nuts. It can be ONLY in dependencies. After deleting it from dev dependencies, do npm install. It will work without any issues.

Nuxt app failed heroku deployement code=H10 error

I'm trying to deploy my ecommerce nuxt app to heroku. Here's exactly what I did
heroku create myapplok
heroku buildpacks:set heroku/nodejs -a myapplok
heroku config:set HOST=0.0.0.0 -a myapplok
/// everything works fine
then
$ git init
$ heroku git:remote -a myapplok
$ git add .
$ git commit -am "make it better"
$ git push heroku master
I followed exactly what the heroku website did list. Everything works

Once I visit the link, however, I get an error:
After following the heroku tail command, the app keeps crashing with the following error

Now i know that this problem has already been solved with this command in my nuxt config app
server: {
port: process.env.PORT || 4002,
},
I did add the process.env.port command but I'm still getting this error.

Remove heroku config:set HOST=0.0.0.0 -a myapplok
because your nuxt app runs in configured to run on localhost

Thanks you if you can help me or give me any advice

From your heroku logs looks like you have issues with webpacker. As you can see here

2019-05-22T13:56:04.512182+00:00 app[web.1]: 1. You want to set webpacker.yml value of compile to true for your environment

2019-05-22T13:56:04.512185+00:00 app[web.1]: 3. You have misconfigured Webpacker's config/webpacker.yml file.
2019-05-22T13:56:04.512186+00:00 app[web.1]: 4. Your webpack configuration is not creating a manifest.
Did you run webpacker:compile command on heroku?
Also based on info here https://github.com/rails/webpacker/issues/1494. There may be an issue with webpacker itself.

How to deploy app to heroku with MongoDb/Mlab

I am having trouble deploying my Node.JS app to Heroku, I know it's the database that is causing the issue but can't work out why. I am led to believe that I need to use Mlab instead of MongoDB Atlas so I have now tried both and neither work. When I deploy and visit the url I get an error. Here are the logs:
2019-04-13T21:42:47.139176+00:00 app[web.1]: operationTime:

Here is my URI for connecting to the DB:
require('dotenv').config();
const dbpass = process.env.DB_PASS;
const mlabpass = process.env.MLAB_PASS;
module.exports = {
MongoURI:
`mongodb://fishj123:${mlabpass}#ds149885.mlab.com:49885/heroku_26921dvn`,
};
Link to my git repo: https://github.com/fishj123/personal-blog
Would really appreciate any help.

For anyone having similar issues - I worked out what was wrong. I hadn't set my Global Variables within Heroku, I hadn't realized that this was necessary.
Setting the variables in Heroku is as easy as going to the Settings tab and then setting the variables under Config Variables.
