Cogfy Messenger

Overview

The node provides functionality to retrieve a specific chunk of embedding data by its unique identifier. This operation is useful when you need to fetch detailed information about a particular chunk from a collection of embeddings, for example, to analyze or process that chunk further in your workflow.

Common scenarios include:

• Retrieving a specific piece of vectorized data for similarity search or machine learning tasks.
• Accessing metadata or content associated with a particular embedding chunk.
• Integrating with systems that store embeddings and require fetching individual chunks on demand.

Properties

Output

The output will contain a JSON object representing the embedding chunk corresponding to the provided Chunk Id. This typically includes the chunk's data fields such as vector values, metadata, or any other relevant information stored within that chunk.

If the node supports binary data output (not evident from the provided code), it would represent the chunk's raw or encoded data accordingly.

Dependencies

• Requires an API key credential to authenticate requests to the Cogfy Messenger API.
• The base URL for the API must be configured in the node credentials.
• Depends on the external Cogfy Messenger API service to fetch embedding chunks.

Troubleshooting

• Invalid Chunk Id: If the provided Chunk Id does not exist or is malformed, the node may return an error or empty result. Verify the Chunk Id value before execution.
• Authentication Errors: Ensure that the API key credential is correctly set up and has sufficient permissions.
• Network Issues: Connectivity problems with the Cogfy Messenger API endpoint can cause failures; check network access and API availability.
• Unexpected Response Format: If the API changes its response structure, the node might fail to parse the output correctly.
