I need to programmatically create a staging site with firebase for CI/CD. I can get multiple hosting sites to work as described here in the docs: https://firebase.google.com/docs/hosting/multisites
However this process requires me to go to the firebase web app and use the GUI to create a new hosting-site.
e.g. running:
firebase deploy --only hosting:<target>
will result in
"Error: HTTP Error: 404, Requested entity was not found."
without manually adding the configured ".firebaserc chosen resource-name" in the web app.
How can I programmatically create a hosting site without the firebase web app involved?
