Made a fork of project to customize tree styling, but getting "Minified React error #130"

Hi there,

Made a fork of the project to customize the hierarchy, but since hosting in a private repository, I was trying to have yarn manage these, but I keep getting:

Error: Minified React error #130; visit https://reactjs.org/docs/error-decoder.html?invariant=130&args[]=undefined&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

The command I am using to build the application is simply `yarn run build`. Thoughts?

I tried tinkering with the webpack and babel configs as suggested in some posts, but I am still getting the same error.

Thank you in advance for any insights.
