Eventarc to trigger Cloud Run by Firestore document creation event
I am trying to set up a basic Eventarc trigger for triggering Cloud Run when a new Firestore document is added.
I set it up as depicted in the screenshot below (region: global; resource: any). Then I create a new document in Firestore (database location: europe-west3).
