Knowledge Base → Get Document Chunk

AI-generated

Overview

The "Get Document Chunk" operation in the Knowledge Base resource allows users to retrieve a specific chunk of a knowledge base document by providing the document's ID and the chunk's ID. This is useful when working with large documents that are divided into smaller chunks for easier management, search, or processing. For example, if you have a large technical manual stored in your knowledge base, you can fetch only a relevant section (chunk) instead of loading the entire document, improving efficiency and response times.

Properties

Name Meaning
Document ID The unique identifier of the knowledge base document from which to retrieve a chunk.
Chunk ID The unique identifier of the specific chunk within the document to retrieve.

Output

The output JSON contains the data of the requested document chunk. This typically includes the content of the chunk and any associated metadata defined by the knowledge base service. The node does not explicitly mention binary data output for this operation, so the output is expected to be purely JSON structured data representing the chunk.

Dependencies

  • Requires an API key credential for authenticating with the ElevenLabs Conversational AI API.
  • Relies on the internal KnowledgeBaseService to perform the actual retrieval of document chunks.
  • No additional environment variables or external services are explicitly required beyond the configured API authentication.

Troubleshooting

  • Common Issues:
    • Providing invalid or non-existent Document ID or Chunk ID will likely result in errors or empty responses.
    • Network or authentication failures due to incorrect or missing API credentials.
  • Error Messages:
    • Errors related to "document not found" or "chunk not found" indicate that the provided IDs do not match existing records; verify the IDs.
    • Authentication errors suggest issues with the API key credential setup; ensure the API key is valid and correctly configured in n8n.
  • To resolve these, double-check input parameters and credential configurations.
