Deployed React app to github pages is blank

I’m following instructions from https://github.com/gitname/react-gh-pages to deploy my react app to github pages.

At the link I’m getting a blank page though and a 404 error: Failed to load resource: the server responded with a status of 404 ()

My app works on local host

I searched around and its likely my homepage link that is wrong?

link to my repo: https://github.com/PatgioK/pathfindingvisualizer

link to the app: https://patgiok.github.io/pathfindingvisualizer/

here is my package.json:

  "name": "pathfindingvisualizer",
  "version": "0.1.0",
  "private": true,
  "homepage": "https://patgiok.github.io/pathfindingvisualizer/",

  }
}

Answer

Try specifying the branch in the deploy script by adding -b SomeBranchName in your packages.json.

so:

"scripts": {
    ...,
    "deploy": "gh-pages -d build -b SomeBranchName",
    ...
