I tried to the individual chat conversation with another user in odoo14CE. But I am not able to continue the chat conversation with that same user. 

I am getting the error message attached below.

Error: Cannot create/update record with data unrelated to a field. (model: "mail.message_seen_indicator", non-field attempted update: "threadId")
