Overview

The node "Zep Memory" integrates with the Zep AI Memory Service, allowing users to manage and interact with memory data related to AI sessions. Specifically, for the Memory - Get operation, it retrieves the stored memory messages associated with a particular session ID.

This node is useful in scenarios where you want to fetch the conversation history or memory state of an AI session to provide context-aware responses or analyze past interactions. For example, in chatbot applications, retrieving session memory can help maintain continuity in conversations by accessing previous user inputs and assistant replies.

Properties

Name Meaning
Session ID The unique identifier for the session whose memory you want to retrieve.

Output

  • The output JSON contains the memory data retrieved from the specified session.
  • This typically includes an array or object representing the stored messages or memory content linked to that session.
  • The exact structure depends on the Zep AI Memory Service response but generally represents the conversation history or memory entries.
  • No binary data output is involved in this operation.

Dependencies

  • Requires an API key credential for authenticating with the Zep AI Memory Service.
  • The node uses the base URL and API key from these credentials to make HTTP requests.
  • Proper configuration of the API key credential within n8n is necessary for successful operation.

Troubleshooting

  • Common issues:

    • Invalid or missing session ID will result in errors or empty responses.
    • Incorrect or expired API key credential may cause authentication failures.
    • Network connectivity problems can prevent communication with the Zep service.

  • Error messages:

    • Authorization errors indicate issues with the API key; verify and update the credential.
    • Not found errors suggest the session ID does not exist; confirm the session ID is correct.
    • JSON parsing errors may occur if input parameters are malformed; ensure valid JSON where applicable.

  • To resolve errors, check the session ID validity, ensure the API key is correctly set up, and verify network access to the Zep service endpoint.
