I received this code error each time I tried to deploy may app on Heroku:code: 'ERR_DLOPEN_FAILED'

Question

I am new in Heroku and currently building an app with react (Node.js).

While I was able to push successfully my master branch to Heroku and Heroku confirms my app is deployed successfully, yet, the app is not deployed despite that is shows below deploy success message: "Deploy to Heroku".

Below is the error log in Heroku:

I have tried all tricks including many suggested here but it has not been helpful.

Of course, my package.json has this script. "start": "node index.js",

Could anyone help with a precise solution?

The issue was probably connected the caches in the Node_Modules. I fixed this issue by running this in the terminal:

$ git rm -r --cached .
$ git add .
$ git commit -m "fixed untracked files"

Use bcryptjs instead of bcrypt

$ npm uninstall bcrypt
$ npm install bcryptjs

Regarding the answers that involve using bcryptjs! Make sure you also change the require statement(s) to accurately reflect bcryptjs instead of bcrypt.

$ npm uninstall bcrypt
$ npm install bcryptjs

Above code is what you would need to run in the server component of your app!

Below is the code in the applicable files that require bcrypt but will now require bcryptjs

const <name> = require('bcryptjs');

I received this code error each time I tried to deploy may app on Heroku:code: 'ERR_DLOPEN_FAILED'
