React app deployed to github giving me a minified error #152

hi there!
i am having a problem with my react app. I am trying to deploy the website to github pages but Page but I am getting this error:

Error: "Minified React error #152; visit[]=u for the full message or use the non-minified dev environment for full errors and additional helpful warnings."

I am not sure how to solve this since this is the first time i try to deploy a website. I tried installing some dependencies like Webpack, babel, Parcel to bundle my files into a readable Js file, but my guess is that something is not being translated properly, meaning that there might be a syntax error somewhere in my code.

The error is telling me to use the non-minified dev environment, but I cannot figure out how to do this.

here is a link to my github repository if you would like to check!
