react react Cannot read properties of null (reading 'useState')

 After introducing a new component into our application, we noticed the page throws up an error 

"react Cannot read properties of null (reading 'useState')"

After some troubleshooting and analysis, we noticed that a different react version was deployment. So instead of a single version, we have 2 version and broke it. 

The fix is to change package.json to use the same react version and webpack does it thing!

 While trying to run gemini cli on my windows linux subsystem, i bump into this error here - "/Roaming/npm/node_modules/@google/gemini-cli/node_modules/undici/lib/web/webidl/index.js:512 webidl.is.File = webidl.util.MakeTypeAssertion(File)"  "ReferenceError: File is not defined" In Node.js, there’s no built-in File (until very recent Node 20+ with experimental WHATWG APIs).
