[Bug] Anthropic API Error: Invalid message structure with thinking blocks

Bug Description
I got this error message for a whole day, which completely defeated the purpose of subscribing to the max plan for me. API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.3.content.0: If an assistant message contains any thinking blocks, the first block must be thinking or
redacted_thinking. Found text."},"request_id":"req_011CXTQVFwbC6qhzKPnpUPJk"}
