AI Studio responding with "invalid argument" for every request no matter the form

Does any know why, all of a sudden, I am getting “invalid argument” for any thing I type in to AI Studio?

Edit: It was the chat history. Clearing it cleared up the issue.

did anyone ever respond? i’m still getting this 7 straight days, and now am officially moving away from google ai studio.

did you see that “+” click that and enter a new chat , prolem solved
