When debugging a production build, you can utilize the terminal directly on the production server where the build was initiated. The specific commands and procedures will vary depending on your deployment environment.

Alternatively, you can execute the build locally using Node.js by running node .output/server/index.mjs, which allows you to inspect any errors directly in your terminal.

Furthermore, Nuxt.js frequently outputs error messages to the browser console, so examining the console on the production site is highly recommended.

You can run node with --inspect or --inspect-brk flags, and then connect to it with chrome dev tools, or VS code debugger. Example: node --inspect-brk .output/server/index.mjs
