Dify version

0.15.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I have deployed Dify locally and am trying to retrieve conversation history via the API. The user and conversation_id values are obtained from the Dify admin logs, so I am certain they are correct. However, when calling the /v1/messages API, it returns a 404 error with the message "Conversation Not Exists." Additionally, the /v1/conversations API returns an empty list, indicating no conversations exist for the user. Upon investigating the PostgreSQL database, I found that the from_end_user_id in the conversations table does not match the provided user ID, and the user ID I used matches the session_id in the end_users table, which seems incorrect and confusing.
