Error: Tuple Indices Must Be Integers or Slices in Chatbot Responses

[lydacious]

Hello,
So I am running main.py with langchain and after I inserted an md file I was able to ask it a question. However, when I try to ask a second question, I get this response:

  {
    "status": true,
    "msg": "Something went wrong:\ntuple indices must be integers or slices, not str",
    "debug": {
      "original question": "Which tech does Lagrange use?",
      "modified question": "Which tech does Lagrange use?",
      "answer": "Something went wrong:\ntuple indices must be integers or slices, not str"
    }
  },
  200
]

P.S Every time I use a new session id, my first question is instantly answered but the second one returns this response.
