Error with running ReactJS/TailwindCSS/Heroku: React Refresh runtime should not be included in the production bundle

Question

Working on a webfolio in ReactJS using TailwindCSS. Deployed it to Heroku, builds successfully, but opening the App always gives the error: ERROR: React Refresh runtime should not be included in the production bundle.

Really not sure what I could've done wrong other than not configure tailwindcss to be deployable. I don't have any devdependencies, they're all dependencies.

package.json:

  "name": "webfolio",
  "version": "0.1.0",
  "private": true,
  "dependencies": {

Answer 1

have you checked the package.json scripts, since it has been renamed to CRACO by tailwind.

"start": "node server.js"
