Connect

Establishes a connection to Google Vertex AI service for subsequent API calls.

Common Properties​

  • Name - The custom name of the node.
  • Color - The custom color of the node.
  • Delay Before (sec) - Waits in seconds before executing the node.
  • Delay After (sec) - Waits in seconds after executing node.
  • Continue On Error - Automation will continue regardless of any error. The default value is false.
info

If the ContinueOnError property is true, no error is caught when the project is executed, even if a Catch node is used.

Inputs​

No inputs required for this node.

Options​

  • Credentials - The Google Cloud credentials required to authenticate with the Vertex AI service.
  • Project Id - The Google Cloud Project ID where the Vertex AI service is configured.

Output​

  • Connection Id - A unique identifier for the established connection that can be used by other Vertex AI nodes.

How It Works​

The Connect node establishes a connection to the Google Vertex AI service using the provided credentials and project ID. When executed, the node:

  1. Retrieves the provided credentials and validates them
  2. Extracts the authentication token from the credentials
  3. Gets the project ID from the options
  4. Validates that the project ID is not empty
  5. Creates and stores a client connection with the token and project ID
  6. Returns a unique connection ID that can be used by other nodes

Requirements​

  • Valid Google Cloud credentials with appropriate permissions for Vertex AI
  • A valid Google Cloud Project ID
  • Proper network access to Google Cloud services

Error Handling​

The node will return specific errors in the following cases:

  • Invalid or missing credentials
  • Empty Project ID
  • Authentication failures
  • Network connectivity issues

Usage Notes​

  • The Connection ID output should be passed to other Vertex AI nodes that require a connection
  • The credentials should have appropriate permissions for the Vertex AI services you plan to use
  • The Project ID must match the project where your Vertex AI resources are configured
  • This connection should be established before using any other Vertex AI nodes
  • The connection can be closed using the Disconnect node when no longer needed
