ENOENT error in Next.js 14.0.4: Missing BUILD_ID file

Question

I am encountering an ENOENT error in my Next.js 14.0.4 project related to the missing BUILD_ID file. Here are the details of my project setup:

• Node.js version: 21.5.0
• Next.js version: 14.0.4

[email protected] start next start

▲ Next.js 14.0.4

• Local: http://localhost:3000

[Error: ENOENT: no such file or directory, open 'C:.next\BUILD_ID'] { errno: -4058, code: 'ENOENT', syscall: 'open', path: '\.next\BUILD_ID' }

-Deleted the .next directory and rebuilt the project. -Checked for updates in project dependencies using npm install. -Reviewed and ensured the correctness of my code related to starting the Next.js application.

Answer 1

BUILD_ID is an auto-created file by next build to save unique key for the build. It's located in /.next.

The error you're encountering simply means this file or .next doesn't exist.

To solve:

run npm run build then npm run start.

Note: Don't remove/modify anything in .next folder unless you have a reason. As a beginner you might not have a reason to remove it at all.
