Files will be uploaded to Google Cloud Storage in real-time as results come through. The local file paths (screenshot_path, stored_response_path) in URL results will be replaced with GCS URLs (gs://bucket-name/blob-name).
Authentication: The GCS driver uses the Google Cloud Storage client library which automatically detects credentials. You can authenticate using one of the following methods:
Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to point to your credentials JSON file
Use Application Default Credentials if running on Google Cloud Platform
The client library will automatically detect credentials from your environment
The addons.gcs.credentials_path config option is available but optional, as the client library handles credential detection automatically.
