   I keep having the same issue even after using the modified package.json file. Who can I call or email to fix the issue since< i paid for the course an I really am getting frustrated with this stumping my progress.

   Just ran into this problem, and found something saying that webpack had renamed contentBase to static
   webpack/webpack-dev-server#2958 (comment)

   Making the change in the webpack.config.js file fixed the error for me.

   Ran into this issue as well. Changing the contentBase to static in the webpack.config.js file worked for me as well:

   I was getting an error: "export 'ReactDOM' (imported as 'ReactDOM') was not found in 'react-dom/client' (possible exports: createRoot, hydrateRoot)"

   I resolved by changing this by doing two things:

   1. I change the following statement in Main.js from
      import { ReactDOM } from "react-dom/client";

   to

   import ReactDOM from "react-dom/client;

   so just basically removing the curly brackets from the import statement.

   2. I commented out the following statement in Main.js:
      import { func } from "prop-types";
