Issue: The webhook client used by all webhook connectors uses a Google Cloud Metric API/SDK which is returning an empty response due to a Google Cloud incident. This is required to fetch the oldest unacknowledged message to be able to sync the latest webhook data.
Cause/Impact: All webhook connectors are failing because of this error and not able to sync webhook events. However these events are captured properly and the next successful run should be able to process all these events.
Opened Support ticket with Google.
Response from Google: This is related to an ongoing incident in Google - https://status.cloud.google.com/incidents/rXqQALuw55aCKd2QHfM3
