But 2.0 is experimental, I am very sceptical about using it for production. If this issue is only for streaming, can’t we use generate_content instead of chat_session.send_message

Hey all, we’re looking into this - thanks for reporting

To work around for now, I am using explicitly “'gemini-1.5-flash-001” which is one of stable ones.

Thanks for your patience on this. We just pushed a fix and it should be live soon.
