Hi folks,

Problem

I have an ongoing problem when I am due to publish a new version. I encounter a build error that I haven’t been able to resolve using v0. I even removed the article that seemed to be causing issues, but it didn’t help.

Now, my site’s indexing seems broken; Google Search Console now only finds 7 pages on my website, whereas 3 weeks ago it found 13 pages (out of 80 total). Anyone can help?

Did you know there’s another category dedicated to v0 topics? A human should be here soon to help, but the answer may already be available even faster in one of these other posts.

Our docs are a great place to start.

Yes, I’ve seen this type of issue before with Next.js builds on Vercel.
From the log, the problem is happening during the static export step.
The build is failing when Next.js tries to generate the page:

/articles/[slug]/page

Specifically this article:

aws-d1-4-structural-steel-welding-quality-control

Even though you removed the article, the build process may still be referencing it from somewhere else.

There are a few common causes:

  1. Broken data source
    If the page uses generateStaticParams() or getStaticPaths(), the slug might still exist in your CMS, database, or markdown files. The build tries to generate it and fails.

  2. Undefined data during build
    Sometimes the page expects article data, but the data is undefined. That causes the static export to crash.

  3. Build cache issue
    Vercel sometimes restores an old cache, which still contains references to removed pages.

What you need do to fix it:

Check generateStaticParams() or wherever the article slugs are generated.
Make sure the deleted article slug is not returned anymore.
Add safe checks in /articles/[slug]/page.tsx so the build does not crash if data is missing.
Clear the Vercel build cache and redeploy.Run next build locally to reproduce the exact error.
