Cannot start the basic example (Invalid regular expression)

After following the steps shown in the docs here: https://github.com/scalajs-react-interface/sri/blob/master/docs/GettingStarted.md#native-mobile-app

It ends with this error:

$ yarn start
yarn run v1.21.1
$ react-native start server --transformer scalajsTransformer.js
Looks like you installed react-native globally, maybe you meant react-native-cli
?
To fix the issue, run:
npm uninstall -g react-native
npm install -g react-native-cli
error Command failed with exit code 1.

and.

(And yes, I've tried the uninstall/install step of the react-native-cli plugin)

Running without yarn, yields:

$ react-native start server --transformer scalajsTransformer.js

Maybe I'm missing something of the environment or so, but the page link https://reactnative.dev/docs/getting-started.html is broken.
