# This workflow demonstrates how to use the Firestore connector:
# Create and retrieve a Firestore document
# Export the document to a Cloud Storage bucket (which must already exist)
# Delete the document
# Expected output: "SUCCESS"
- init:
    assign:
      - project_id: ${sys.get_env("GOOGLE_CLOUD_PROJECT_ID")}
      - collection: "example-collection"
      - document: "example-document"
- create_document:
    call: googleapis.firestore.v1.projects.databases.documents.createDocument
