I'm trying to deploy my sapper/svelte app to heroku but getting 'Error: Cannot find module 'polka'' this error. Interesting thing is that, it was perfectly fine and working. My package.json is correct and I am not checking my modules into git either. I tried disabling caching but it is no good. Anyone have any ideas?

It turns out polka's version on my package.json was set to 'next'. So I changed it to it latest stable version and deleted package.lock.json file and ran 'npm install' to create a new lock file and then pushed it to heroku. Works perfectly fine.

The app crashes everytime showing this error. How to fix this?
Follow the below steps in order to use Open CV inside Heroku
Add heroku-buildpack-apt to your Heroku Build packs. You can go to your app's settings page and add build packs.
Create a file named Aptfile and add the following libs: libsm6, libxrender1, libfontconfig1, libice6. Follow the example below:
libsm6
libxrender1
libfontconfig1
libice6
I am using a package from github which is to be install from package.json file. But when I deploy the app on heroku, It is not able to install the package.
In package.json, I tried using different methods as below,
"sqlike": "git+https://username:access-token#github.com/vijjuu/SQLike.git"
"sqlike": "https://github.com/vijju/SQLike#master"
"sqlike": "https://github.com/vijjuu/SQLike/tarball/master"
"sqlike": "vijjuu/SQLike"

1) Your exporting your sql like but not importing it anywhere.
2) You don't have a server like ( node ) to run it on Heroku.
I have a simple REST API deployed in Heroku. It uses MongoDB as the document storage service for the endpoints. It fails to run properly ever since I ran npm install to add another module for a different set of features. It doesn't matter what I do at that point, until I replace the node_modules folder (locally) with an older version before the last time I ran npm install, and re-deploy.

I read at least 10 other articles, and tried downgrading, reinstalling MongoDB with no success.
Issue: my local node_modules folders was being included in my push to Heroku. Once removed, the application runs fine on Heroku:
git rm -r --cached node_modules
git commit -m 'Remove the now ignored directory node_modules'
git push origin master
I am getting a model import error in my Node.js application when deploying to Heroku.

I have tried doing heroku run bash and running require('./models/Comic') from node session in app and require('../models/Comic') from within a subdirectory of /app/routes/ to test that require works.
The only instances of the require for Comic are in the three routes within the routes folder. They all have the exact same var myVar = require('../models/Comic');.
I figured out that heroku:
a) Takes the info from Git. Even though I had made case changes in my local files and pushed to Git, the case wasn't changed. Then when the file was required on heroku which uses Linux, it could not find the file.
b) Only changing the name of the file from heroku run bash didn't seem to have any affect. I am assuming I wasn't doing some sort of deployment step or that I needed to do something extra (I tried heroku restart but no dice).
Hope this can help someone else.
I have this in my express settings
var morgan = require("morgan");
app.use(morgan("dev"));
This works on my development macine, but crashes when I deploy to Heroku:

I can replicate the problem by running node from the Heroku CLI, and trying to require morgan. Anyone have an idea what I'm doing wrong?

Line 16 of index.js reads var debug = require('debug')('morgan').
The debug module does lack an index.js, but has this in its package.json instead
"main": "./node.js",
"browser": "./browser.js",
"component": {
"scripts": {
"debug/index.js": "browser.js",
"debug/debug.js": "debug.js"
}
},
Turns out was something to do with an out-of-date package and updating to latest enabled me to progress
