[bestori]

Demo and tutorial would not run unless this dependency version is updated.

The build fails:

Error: ESLint configuration in .eslintrc » eslint-config-react-app is invalid:
- Property "overrides" is the wrong type (expected array but got

Indeed. Any ideas? @fzaninotto

@bestori,
Upgrading eslint-config-react-app to version 5.2.0 should solve it (current ra version: v4.0.1).
This was fixed in version 3.1.0 of create-react-app when they upgraded to ESLint v6.

Thanks for contributing. But it has been already fixed by #5055. It will be part of the next major release (probably v3.8.0).
