I decided to upgrade my extension to use 2nd generation Cloud Functions. I changed my cloud function from pubsub.schedule to onSchedule.
In extensions.yaml I have to define resources.properties.eventTrigger.eventType. However I am not able to find any hints in the documentation: https://firebase.google.com/docs/extensions/publishers/functions#scheduled
The resources section in my extensions.yaml file.
resources:
- name: backupauthusers
type: firebaseextensions.v1beta.v2function
description: >-
Scheduled function that will backup Authentication users to Google Cloud Storage bucket.
properties:
eventTrigger:
eventType: <What event type?>
buildConfig:
runtime: nodejs18
Some eventTypes I have attempted:
- google.pubsub.topic.publish
- google.cloud.pubsub.topic.publish
They have resulted in deployment errors, I guess the type is invalid:
Extensions deploy had errors:
