Cannot deploy with npm run Deploy in React on github pages

Question

unfortunately I cannot deploy on GitHub my Color-recognition App in React JS on GitHub pages. I am using Webpack as bundler.

My system configuration is: 
Webpack
Environment:
OS: Windows 10
Node: 8.12.0
Yarn: Not Found
npm: 6.4.1
Watchman: Not Found
Xcode: N/A
Android Studio: Not Found
Packages: (wanted => installed)
react: ^16.5.2 => 16.5.2
react-dom: ^16.5.2 => 16.5.2
react-scripts: 1.1.5 => 1.1.5

I use extra added dependencies of Clarifai and Gsap and used the following steps:

I created on my Github account the repository Color-recognition without md file, and within added gh-pages branch, and in setting of repository under Source added gh-pages branch.
git add .
git commit -m "Uploading files"
git push -f origin master:gh-pages
git remote add origin https://github.com/Geeeva/Color-recognition.git npm run deploy

The page should be deployed but it couldn't, with the error below. I wanted to put the project demo that is visible. Tried the same procedure with the master branch of the Color-recognition, and I got the same error.

The error is following:

Cannot read property 'email' of null
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] deploy: gh-pages -d build
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] deploy script.
npm ERR! This is probably not a problem with npm. There is likely additional log ging output above.

npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\Ivana\AppData\Roaming\npm-cache_logs\2018-09-19T19_58_34_ 829Z-debug.log

Link to my Github repo is: https://github.com/Geeeva/Color-recognition

no, i have cloned your repo and changed the url to my git repo and then i force pushed the code to master and after that i have created a branch named gh-pages by taking master as base, in the github UI and made sure that gh-pages branch is used in the settings and then ran the code npm run deploy.. — Shiva Sai

I managed to fix it by setting my git config user name and email. (As the link provided above specifies the need of both).

So just write in the terminal:

git config --global user.name your name

git config --global user.email @youremail
