Briefly, this error occurs when the state of the user’s session in Elasticsearch is not found or is invalid. This could be due to session expiration, server restart, or a mismatch between the session state and the client’s state. To resolve this issue, you can try the following: 1) Ensure the session is still valid and hasn’t expired. 2) Check if the server was restarted, which could have cleared the session. 3) Verify that the client’s state matches the session state. 4) If the problem persists, consider implementing a more robust session management strategy.
