Thanks @taoari for flagging this!

So I'm getting something similar.. when the ChatInterfaces's fn is called, i get this error:

gradio.exceptions.Error: "Data incompatible with messages format. Each message should be a dictionary with 'role' and 'content' keys or a ChatMessage object.

and indeed, my history[] has that metadata component in it too. So in the declaration of fn, I used a lambda function to try to address that by add clean_history() on the history parameter:

def clean_history(history):
# Keep only 'role' and 'content' keys from each history entry
return [{"role": entry["role"], "content": entry["content"]} for entry in history]

gr.ChatInterface(
#fn=respond,
fn=lambda message, history, max_tokens, temperature, top_p: respond(message, clean_history(history), max_tokens_slider.value, temperature_slider.value, top_p_slider.value),
additional_inputs=[max_tokens_slider, temperature_slider, top_p_slider],
type='messages'
)

but I'm still getting the same error...
Any help would be great!

This is running under FastAPI framework. I had this thing running fine with flask, but the app and chatbbot were on different ports. With FastAPI, it's running on the same port by:

gr.mount_gradio_app(app, chatter, "/chat")

where /chat if the src of the iframe it's running in.
