I am attempting to deploy an AI chatbot with a form that would allow me to collect user feedback. Currently, I am able to save the user query and generated chatbot answer to a Mongo DB database, however, when attempting to save the feedback, I am unable to save anything. How could I save the feedback associated with each query and answer pair. Here is my code for the moment:

#init_db is a function to connect to my mongodb database
DB_NAME = "feedback"
COLLECTION_NAME = "ai-chatbot"
feedback_collection = init_db(DB_NAME, COLLECTION_NAME)

def init_messages():
    if 'RAG_messages' not in st.session_state or st.sidebar.button("Eras the conversation"):
        st.session_state.RAG_messages = [{"role": "assistant", "content": "How can I help you?"}]

def save_feedback(question, answer, sources, contexts, feedback_rating, feedback_comment, timestamp):
    feedback_data = {
        "question": question,
        "answer": answer,
        "contexts": contexts,
        "sources": sources,
        "feedback_rating": feedback_rating,
        "feedback_comment": feedback_comment,
        "timestamp": timestamp
    }
    feedback_collection.insert_one(feedback_data)

if is_authenticated():
    st.set_page_config(page_title="AI Chatbot", page_icon="👾")
    st.title("Ask your questions")

    init_messages()

# RAG_qa is a class that represents my RAG chatbot
    RAG_app = RAG_qa()

    for message in st.session_state.RAG_messages:
        st.chat_message(message["role"]).write(message["content"])

    if prompt := st.chat_input("Send a question"):
        st.chat_message("user").write(prompt)
        st.session_state.RAG_messages.append({"role": "user", "content": prompt})

        answer, sources, contexts, urls = RAG_app.retrieval_qa(prompt)

        st.chat_message("assistant").write(answer + '  \n  \n' + sources)
       st.session_state.RAG_messages.append({"role": "assistant", "content": answer + '  \n  \n' + sources})
        st.session_state.RAG_chat_memory_messages = st.session_state.RAG_messages

        with st.form(key='feedback_form'):
            feedback_score = st.radio("Was the answer helpful?", ["Yes", "No"], index=1)
            feedback_comment = st.text_area("Additional comments")
            submitted = st.form_submit_button("Submit Feedback")

            if submitted:
                feedback_rating = 1 if feedback_score == "Yes" else 0
                timestamp = datetime.datetime.now().isoformat()
                save_feedback(
                    question=prompt,
                    answer=answer,
                    urls=urls, 
                    contexts=contexts,
                    feedback_rating=feedback_rating,
                    feedback_comment=feedback_comment,
                    timestamp=timestamp
                )
                st.success("Thank you for your feedback!")
else:
    st.write("Please log in from the homepage to access this page.")

I think you can provide a complete example instead of partial code. We cannot find exceptions through code snippets. Thank you.
