When running npm run build on a project where I've changed something on its package.json, produces the exact same output as if I hadn't done any changes after running npm run build again.
I'm trying to upload the build folder to Pinata and it's producing the same hash (CID), so both folders (pre and post modification) are exactly the same.
What could be happening here?
This is my package.json file:

Thanks!
npm run build just runs react-scripts build.
If you updated your dependencies, you need to npm install or npm update them first.
background: I did coding for ReactJS app and wanted to deploy on Netlify or Vercel. When I npm run build, I got error.
npm run build error
When I typed npm audit fix, I got this.

First MERN app. Having trouble deploying to Heroku. Everything worked when running locally. I've tried uninstalling/reinstalling react-bootstrap. What could be the problem?
