next.config.js file gets altered when deploying

[lauroaraujo]

After changing my build command to a custom npm script yarn now:build, which just calls standardjs to lint the code before deploying (standard && next build), my build started breaking with linter errors on the next.config.js file.

Nothing breaks locally, and the errors reported do not match the next.config.js file in our repositories.

This happens both in the github integration and deploying locally with now

Does Now changes the next.config.js file in any way before deploying? Is this documented somewhere?

Hi @lauroaraujo we'll gladly take a look at your issue. Can you please send us an email to support@vercel.com with deployment URLs so we can take a look at your build logs?

We don't modify next.config.js files when deploying.
