When attempting to launch my application on Heroku, I consistently encountered the following error code: 'ERR_DLOPEN_FAILED'

As a new user on Heroku, I am currently working on building an app with react (Node.js).

Even though Heroku confirms that my app has been successfully deployed, the app itself does not seem to be deployed despite showing a deploy success message: "Deploy to Heroku".

Below is the error log from Heroku:

2022-02-08T00:45:18.702341+00:00 app[web.1]:     at Module.load (node:internal/modules/cjs/loader:981:32)
    ...
2022-02-08T01:07:27.610735+00:00 app[web.1]: }
2022-02-08T01:07:27.789789+00:00 heroku[web.1]: Process exited with status 1
2022-02-08T01:07:27.876090+00:00 heroku[web.1]: State changed from starting to crashed

The CLI also displays an error log:

2022-02-08T00:45:12.986742+00:00 app[web.1]: ^
    ...
2022-02-08T01:07:27.610735+00:00 app[web.1]: }
2022-02-08T01:07:27.789789+00:00 heroku[web.1]: Process exited with status 1
2022-02-08T01:07:27.876090+00:00 heroku[web.1]: State changed from starting to crashed

Despite trying various solutions, none have been effective in resolving the issue.

In my package.json file, the script "start: node index.js" is included as expected.

If anyone can provide a precise solution, I would greatly appreciate it.

Answer №1

Removed bcrypt and installed bcryptjs in my project using npm commands.
Everything's running smoothly with nodejs version 16.16.0

Answer №2

The problem may have been related to the caches in the Node_Modules. To resolve this issue, I executed the following commands in the terminal:

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

Answer №3

Opt for bcryptjs over bcrypt for enhanced security

$ npm uninstall bcrypt
$ npm install bcryptjs

Answer №4

When utilizing bcryptjs for your answers, be sure to update the require statement(s) to accurately reflect bcryptjs instead of bcrypt.

$ npm uninstall bcrypt
$ npm install bcryptjs

The above code is necessary in the server component of your application!

Below is the code within the relevant files that currently require bcrypt but will now need to require bcryptjs instead.

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