TypeError: Cannot read property 'hash' of null, webpack-CodePudding

I am trying to build my nextjs project but its failing every time. Project works without a single error in development but fails in build. Tried deleting node_modules and reinstalling packages but no luck.

After long searching I finally found duplicate of this, but it has been removed by its author.

Fixed it by clearing the vercel build cache by using the --force flag during deployment.

Deleting .next/ dir solved my problem.
