Unable to Get ChatGPT4 Setup

I have successfully setup the LLM Prompter and received results using the Open AI Chatgpt 3.5 turbo model.

However, when i try to change it to Open AI Chatgpt 4 model in “Open AI Chat model connector” and use the “Chat Mode Prompter node” i receive an error “Execute failed: Error code: 400 - {‘error’: {‘message’: “Invalid value: ‘Cla…ion’. Supported values are: ‘system’, ‘assistant’, ‘user’, ‘function’, and ‘tool’.”, ‘type’: ‘invalidrequesterror’, ‘param’: ‘messages[0].role’, ‘code’: ‘invalid_value’}}” Like to seek some advise where did i go wrong with my settings?
