After running npm run dev I get this error
` Failed to compile

Module not found: Can’t resolve ‘react-server-dom-webpack’
Import trace for requested module:

Im attempting to make a chart render on my page.tsx file and im not really sure what index.js does so right now im assuming its auto generated by chart.js. Im currently attempting to make a line chart render with the respective data points in the const data

Below are the possibilities,
I will assume you are using the relatively latest node version and npm version. Otherwise, edit your question and let us know what versions are you using and on which OS.
Based on my assumptions: since you have commented out the line:
Import useClient from react-server-dom-webpack
That is the reason why you are getting this error. The npm can not find this module you have commented out. I suggest you do the below:
npm install react-dom react
npm run start
