Cannot deploy Next.js to Netlify. Deploy failed due to an error in @netlify/plugin-nextjs plugin

Question

I can run npm run build with no problems at all, but whenever I try and deploy my Next.js project to Netlify I get an odd error stating Deploy failed due to an error in @netlify/plugin-nextjs plugin

After doing some research I found that I should install @netlify/plugin-nextjs into my package.json as a dev dependency, then add it to a netlify.toml in the root of my project which I have done. Here is the github repo which Netlify's support forums have led me to: https://github.com/netlify/netlify-plugin-nextjs

I've followed the directions on their github repo above for the @netlify/plugin-nextjs plugin as well as searched for any relevant posts under their github issues and unfortunately I couldn’t find anything related nor useful in the github issues.

I’ve tried clearing cache and deploy but it didn’t help.

I am using Next.js version v11.1.2

Here is the build log with the error detailed:

Here is my netlify.toml:

[build]
publish = ".next"

[[plugins]]
package = "@netlify/plugin-nextjs"

Answer 1

I had this same issue. Removing the @netlify/plugin-nextjs from the plugins tab on Netlify fixed the issue for me. I removed the plugin and triggered a new deploy.

Answer 2

I had the same issue and I resolved it by updating the plugin from the plugins tab in Netlify.

Answer 3

In my case, the solution was to disable the plugin, and then re-enable it. Disabling the plugin broke my site temporarily because it's needed to run Next.js, but it was the only way I could get my deploy to succeed.

Other things I tried that did not work:

• Re-building node_modules
• Updating package-lock.json
• Triggering a re-deploy without cache

Answer 4

If you are using a monorepo to fix this issue go to the deploy settings of your site and under build settings change the publish directory to

[subdir]/.next

where [subdir] is the sub directory you have your next project in.

After that clear change and deploy again

Answer 5

I have faced the same issues. I tried adding the NETLIFY_NEXT_PLUGIN_SKIP= "TRUE"to the environment variables and it worked for me
