My React App shows white page on deployment (Vercel & Others)

[aviralmehrotra]

I’m having trouble deploying my React app. It runs perfectly on my local machine, but when I deploy it on Vercel or other hosting platforms, it just displays a blank white page. I’ve tried some solutions, but nothing seems to work.
GitHub Repository: https://github.com/AviralMehrotra/Retro-Flix
Deployment: https://retro-flix.vercel.app/

Deployment Platforms Tried: Netlify, Vercel, GitHub Pages
Issue: The deployed app only shows a white screen with some errors in the browser console, which I don’t know how to fix. But the app is working without any errors on localhost.

      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "gh-pages": "^6.0.0"
  }
}

What I’ve Tried:
*Deploying directly from the GitHub repository.
* Deploying from the build folder.
* Checked the logs, but no specific errors were reported.
* Tested on different browsers, but the issue remains.

You have to remove the homepage property in package.json if you are using Vercel. Other than that your repo works just fine on Vercel for me.

Sir I am also facing the same error, I also haven’t included the homepage property in my package.json But still it is showing the white blank page on deployment server.
The ‘build’ is running perfectly fine on my local machine (by using Go live feature of VS Code). Please help me, I tried all possible solutions.
