Connect
Establishes a connection to Google Vision API service for subsequent image analysis operations.
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 Vision API service.
Output
- Vision Id - A unique identifier for the established Vision API client connection that can be used by other Vision nodes.
How It Works
The Connect node establishes a connection to the Google Vision API service using the provided credentials. When executed, the node:
- Retrieves the provided credentials and validates them
- Creates a new ImageAnnotatorClient using the Google Cloud Vision API
- Stores the client connection and assigns it a unique ID
- Returns the unique Vision ID that can be used by other nodes
Requirements
- Valid Google Cloud credentials with appropriate permissions for Vision API
- Enabled Vision API in your Google Cloud project
- Proper network access to Google Cloud services
Error Handling
The node will return specific errors in the following cases:
- Invalid or missing credentials
- Authentication failures
- Network connectivity issues
- Vision API service errors
Usage Notes
- The Vision ID output should be passed to other Vision nodes that require a connection
- The credentials should have appropriate permissions for the Vision API services you plan to use
- This connection should be established before using any other Vision nodes
- The connection is managed internally and doesn't require explicit disconnection
