Problem to build the app

[Xam-Mlr]

Hi, First of all thank you for your tutorial it was really useful. My app is working perfectly for now but i'd like to compile so users can start it easily. I saw some other tutorials to build it but just by building react i notice that there are already some issues:

**> react-scripts build

Failed to compile.

fs.copySync is not a function

npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] build: react-scripts build npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] build script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in: npm ERR! /Users/XXX/.npm/_logs/2022-06-28T07_49_49_642Z-debug.log**

And for the complete log:
