Just re-confirming: you've tried rm -rf node_modules yarn.lock package-lock.json and re-installing, and the error is still the same?

[mat2718]

Yes that is correct. I've also tried deleting the whole folder and rerunning the npx command and the problem persists

hello!

turns out the file fp/_baseConvert is missing in the lodash library 4.17.21 but is present in lodash 4.17.15. the wait-on library is the library that has the loadash dependency. long story short i added a resolution to the package.json and set lodash to 4.17.15 and the server started right up

"resolutions": {
    "lodash": "4.17.15"
  },

[Josh-Cena]

Thanks for looking into this. Weirdly, I do see node_modules/lodash/fp/_baseConvert.js in my node_modules, even with lodash 4.17.21. Unfortunately, because this issue is entirely external (it's caused by a lodash-internal import, which itself is triggered by an import from wait-on), we cannot act on this even if it turns out to be valid (which I can't verify). I'm going to close this since you've figured out how to patch it; let's see if someone else complains in the future. Worth noting that lodash 4.17.21 was released two years ago and no one else had been complaining about this, so there's probably something wrong during your installation process.
