Vercel Build Not Working

Vercel builds not working and I haven’t done any ground breaking changes.

My Next.js builds work locally and I even disabled --turbopack from my build command, but it’s still throwing me errors like it can’t find tailwind, etc…

It was working earlier and now its failing across all branches including ones that worked previously.

For example I deleted a console.log and pushed it to see if it would work and it failed.

Please help, I also have all dependencies installed and haven’t changed my nextjs.config.mjs at all.

Example logging (with npm run build without turbopack)

⚠ Support for Turbopack builds is experimental. We don't recommend deploying mission-critical applications to production.

22:09:26.741

22:09:26.741

- Turbopack currently always builds production sourcemaps for the browser. This will include project sourcecode if deployed to production.

22:09:26.741

- It is expected that your bundle size might be different from `next build` with webpack. This will be improved as we work towards stability.

22:09:26.741

- This build is without disk caching; subsequent builds will become faster when disk caching becomes available.

22:09:26.742

- When comparing output to webpack builds, make sure to first clear the Next.js cache by deleting the `.next` directory.
