Description
ChatSummaryMemoryBuffer._summarize_oldest_chat_history is crashing due to sending a single message with role system while Anthropic expects also a user message. Also current implementation is missing the instruction to summarize (summarize_prompt) which I added as role: system and moved context to next message as role: user
