Hi! I'm trying to test this using the exmple.nt file, when I try to do so in the Webapp I get the following error:

JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Traceback:

File "/usr/local/lib/python3.10/dist-packages/streamlit/runtime/scriptrunner/script_runner.py", line 565, in _run_script
    exec(code, module.__dict__)
File "/home/javi/Desktop/rdf-qa/app.py", line 35, in <module>
    render_gui()
File "/home/javi/Desktop/rdf-qa/app.py", line 24, in render_gui
    data = requests.post("http://localhost:5050/index", files={'file': uploaded_file}).json()
File "/usr/local/lib/python3.10/dist-packages/requests/models.py", line 975, in json
    raise RequestsJSONDecodeError(e.msg, e.doc, e.pos)

After some review, I've found that this is due the Webapp is receiving response 500, therefore, I've checked only the server with the following code:

import requests

files = {'file': open('./rdf-qa/example.nt','rb')}
r = requests.post('http://localhost:5050/index', files=files)

The received answer is:

<!doctype html>
<html lang=en>
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

And the server shows the following error:

ERROR:server:Exception on /index [POST]

Am I doing something wrong? or maybe missing the version of some package?
The received file is properly being stored in the uploads folder, but the error seems to be triggered on the following line:

        index = GPTSimpleVectorIndex(document)

Hi, I believe the Llama Index library introduced breaking changes. Try installing llama-index==0.4.20.
