I get the "Page not found" error after using Next.js Runtime - v5.1.2

Support

1

I am using “next”: “^14.2.3”, “react”: “^18.3.1”, but netlify did not auto apply the newer runtime and kept on using Next.js Runtime - v4.41.1.
The site was built and hosted perfectly fine, but I wanted to try out Next.js Runtime 15, so I updated netlify/plugin-nextjs to “^5.1.2”.
It was build and deployed without any error, and the build log says it was using Next.js Runtime - v5.1.2, but now it has a 404 error.

Thanks for reaching out! Can you let us know if you made any other changes between the working and non-working deploys apart from updating the runtime & next versions?

It looks like the reason for the 404s is that there is no index.html file making its way to the publish directory, e.g: Netlify App, and I wouldn’t expect the runtime update to have an impact on that. Looking forward to hearing from you!

Can you try to add the output line in your next.config.mjs file of your project:

const nextConfig = {
  output: 'export',
  images: { unoptimized: true },
}

And after change the publish directory in your build settings of netlify to out

Sorry for my late reply.
I down graded “@netlify/plugin-nextjs”: “^5.2.0” to “@netlify/plugin-nextjs”: “^4.41.1”
=> It started using Next.js Runtime - v4.41.1 and shows the site.
I re-upgraded “@netlify/plugin-nextjs”: “^4.41.1” to “@netlify/plugin-nextjs”: “^5.2.0”
=> It started using Next.js Runtime - v5.20.0, doesn’t show any build nor deploy errors, but now it does not show the site with a 404 error.
The only difference I made is the version of @netlify/plugin-nextjs, so I guess it is related to the plugin, or the runtime.

Thank you for your reply dietercasier.
I am currently using Next-auth, and when I enable “output: ‘export’,”, it shows the error so I didn’t use it.
Error: Page "/api/auth/[...nextauth]" is missing "generateStaticParams()" so it cannot be used with "output: export" config.
It is strange, because it doesn’t mension about generateStaticParams() on the official document.
I guess NextAuth and output: ‘export’ cannot be used together.

I did some research, and I guess “output: ‘export’ makes the app to be completely SSG, so it doesn’t work with NextAuth.
I disabled NextAuth, and set the “output: ‘export’ in order to check wether the site deploys, and it still has the 404 error.
As a conclusion, I believe it is something around @netlify/plugin-nextjs or the runtime v5.

Hi @aki,

Thanks for following up.

I’m unable to reproduce an issue with Next.js 14 and the version 5 of the plugin. Here’s a repo of mine where I’m using Next.js 14.2.3 and the Netlify/Next.js runtime v5.2.1 (which is the latest version). However, I’m not getting a page not found when visiting the site.

Have you seen our Support Guide here:

It can help troubleshoot the issue with the Page not found if you could give it a read.

10

Thank you for your support Melvin.
I did read the Support Guide, but maybe I should give it an another try.
I will going to be busy for this couple of days so please understand that it might take a while.

P.S. I have been using the netlify Support Forums, and I am surprised that there is always a quick reply, whether it’s from a Support Engineer or a User.
I really appreciate the great community you guys are building, keep up the good work!

@aki we love to hear that! If you encounter more questions after taking a look at it further, feel free to let us know!
