Forgive me if this is obvious , as I am fairly new to railway.

I recently have been working on my resume website. I made a few minor changes and suddenly my deploy is failing with this error. I did not change anything that should have broken my app.

Edit: the issue was that railway was using the wrong node version. I have since fixed it and it is no working.

Try:

Add a package.json field to lock your Node version:

"engines": { 
     "node": "20" 
}

Or be more specific if needed:

"engines": { 
    "node": "20.11.1"
}

You can also set the version with NIXPACKS_NODE_VERSION=20.11.1 as an environment variable in Railway.

crypto.hash is only available in Node.js v16.17.0+ (or better, v18+).

Older versions like v14 or early v16 don't have this method.
In your package.json set engines for latest nodejs version
"engines": {

"node": ">=18.0.0"

}

And if you want to update in Railway only

  • Go to your project settings

  • Find the Environment or Build Settings

  • Set the Node version to 18 or higher
