This is the code copied from your repo :

@cl.on_chat_start async def start(): chain = qa_bot() msg = cl.Message(content="Starting the bot...") await msg.send() msg.content = "Hi, Welcome to School Assist Bot. What is your query?" await msg.update()

cl.user_session.set("chain", chain)

@cl.on_message async def main(message): chain = cl.user_session.get("chain") cb = cl.AsyncLangchainCallbackHandler( stream_final_answer=True, answer_prefix_tokens=["FINAL", "ANSWER"] ) cb.answer_reached = True res = await chain.acall(message, callbacks=[cb]) answer = res["result"] print(answer)

sources = res["source_documents"]

# if sources:
#     answer += f"\nSources:" + str(sources)
#     #pass
# else:
#     answer += "\nNo sources found"

await cl.Message(content=answer).send()
