Git repository not initialized with create-react-app

[vzro]

Describe the bug

npx create-react-app mywebapp returned this at the end of the installation.
I own the directory and it has the right permissions.
git - along with npm, npx - are all updated and working fine on their own, except for this.

The problem happens when you have empty global git credentials.

The workaround is to set it globally (with git config --global user.name user and git config --global user.email user@email.com).

The expected behavior should be: The git repository is created even if global git credentials are note present. Let the user determine the local credentials manually.
