Nextjs Deployment Failed

Hey Railway Team,

I’m unable to deploy my Next.js application on Railway. During deployment, I keep getting an error saying that a security vulnerability is detected and it suggests upgrading Next.js to v15.2.8.

I’ve already upgraded my project to Next.js 15.2.8, verified it in my package.json, reinstalled dependencies, and redeployed — but I’m still getting the same error.

This is extremely frustrating because my client’s production app is currently down, and I’m blocked from deploying any fixes.

Things I’ve already tried:

  • Upgraded Next.js to 15.2.8

  • Redeployed multiple times

  • Confirmed the version locally and in package.json

If anyone has faced this issue before or knows a solution/workaround, please help. This is urgent.

Thanks in advance

Did you push the fix that updates Next to 15.2.8?

Delete your package-lock.json file and node_modules file (locally) and run npm install.

The problem is a mismatch between the lock file and the package.json file.

And then push the new package-lock.json file

It's not always a mismatch, you could also have transient dependencies that depend on a vulnerable version.
