# This workflow demonstrates how to use the Cloud Functions connector:
# Create a function using source code stored as a zip archive in a
# Cloud Storage bucket (gs://BUCKET_NAME/cloud-function-source.zip)
# Source code must be a properly structured Cloud Function
# Expected output: "SUCCESS"

  params: []
