Console error related to Codeium requests

[lihebi]

This error is printed a lot of times. It appears to me that multiple Codeium requests are sent and some throw errors. Related to #328

Yeah, I also tried to fix them a week ago. But I have no idea, the official Codeium chrome plug-in shows the same bug when you interrupt the process of auto-completion (e.g., reject the completion fast and type other characters). I guess the issue roots from the server-end, let me investigate their source code when I have time.
