Zep Memory

Overview

This node integrates with the Zep AI Memory Service to manage user data. Specifically, the User - Update operation allows updating an existing user's details such as email, first name, last name, and additional metadata. This is useful in scenarios where user information needs to be kept current, for example, updating contact details or enriching user profiles with extra metadata.

Practical examples include:

• Updating a user's email address after they change it.
• Adding or modifying metadata related to user preferences or settings.
• Correcting typos in user names.

Properties

Output

The node outputs a JSON object representing the updated user record returned by the Zep AI Memory Service API. This typically includes the user ID, updated fields (email, first name, last name), and any associated metadata.

No binary data output is produced by this operation.

Dependencies

• Requires an API key credential for authenticating with the Zep AI Memory Service.
• The node configuration must include the base URL of the Zep API and the API key.
• Network access to the Zep API endpoint is necessary.

Troubleshooting

• Common issues:

  • Invalid or missing User ID will cause the update request to fail.
  • Malformed JSON in the Metadata field can cause parsing errors.
  • Network or authentication failures if the API key is invalid or missing.

• Error messages:

  • "error": "User not found" indicates the specified User ID does not exist; verify the ID.
  • "error": "Invalid JSON" suggests the Metadata input is not valid JSON; ensure correct formatting.
  • Authentication errors usually indicate problems with the API key; check credentials.

To resolve these, ensure all required fields are correctly filled, JSON inputs are valid, and API credentials are properly configured.
