What issue are you seeing?

I'm using ChatGPT work, normally when this error appear:

[ObjectParam] [input[9].namespace] [unknown_parameter] Unknown parameter: 'input[9].namespace'.

Important: I'm using it in Spanish, sometimes it appears when I change model within the conversation. Also, if I try to continue in a new chat, the error does not dissapear.

I'm ChatGPT work heavy user, it is perfect but, having this kind of error is a pain. I'm working only on projects folders to avoid losing context.

Seems to be tied to resuming a previous thread - no matter the prompt you get the ObjectParam error thrown. I started a new thread in the same project and am not seeing the issue.
