Resolve React Build Errors

My React app builds fine in development but fails the moment I trigger a production build, blocking any chance of pushing it live. I know the problem sits somewhere in the build step—Webpack / Babel throws red errors—yet I’m still not sure whether the culprit is a hidden syntax slip, a missing module, or an overlooked ESLint rule. Rather than spending more time guessing, I’d like an experienced React engineer to jump in, pinpoint the exact build errors, and get the project ready for deployment.

You’ll have full access to the repo and the current build logs. I need you to reproduce the failing build locally, track down and fix every issue, then generate a clean production bundle. A short summary of what went wrong and how you resolved it is important so I can avoid the same pitfalls later.

Deliverables
• Fixed codebase that passes npm run build (or yarn build) without errors
• Notes or PR comments explaining each change
• Proof of a successful production build (terminal screenshot or hosted preview)

If you can turn this around quickly and walk me through the fixes, let’s get started—I’m eager to push the site live.
