I'm developing a Next.js application (with create-react-app) and I want my code not to be seen in the browser (browser -> sources).
I set the environment variable GENERATE_SOURCEMAP = false and locally this solution works perfectly for me (dev and build).
When I deployed the application to Vercel hosting and set the environment variables, then that solution does not work, ie. my code is visible in the browser.
I think Vercel wraps all environment variables with "", so it's possible that this is causing the problem.
How to solve this problem?
