Chapter 3 - TypeError for dev server

[martinbrose]

When I started the dev server, I received the following error:
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined

I had to change the package.json file to state "react-scripts": "3.4.0".
This should be probably changed in branches ch3-initial and ch3.

as far i know u should not change any json file of react, the json files are connected to each other and do some following work by the data of other json files.... So you should not change any react json files.. They may effect your server..
Hope was helpful!
