there! I bought some template from themeforest and everything works fine with previews version, but with the new one I'm having error like 

> TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type

I believe that template is not supposed to have this error, but still I have it. What could be the problem?

  • You need to provide the code. From the surface, it is complaining about `validators.js` at the function `validateString` where the `path` argument is undefined. – Dan Feb 18 '20 at 00:35

You can check this link https://github.com/ionic-team/ionic/issues/20503

To fix this issue simply upgrade to "react-scripts": "^3.4.0"

  1. Overwrite the existing "react-scripts": "^3.x.x" with"react-scripts": "^3.4.0" in your package.json
  2. Delete your node modules
  3. Finally run npm install or yarn install into your command prompt.

i hope it will fix it.
