I am trying to write a streamlit app that takes a prompt, takes a photo, and then run a GPT-4 Vision analysis on the photo. The app does not run beyond line ~13 (the screen just stops after the photo is taken, with no traceback). Would anyone know what the issue might be?

import streamlit as st


import base64
import requests

# OpenAI API Key
api_key = "xxx"

title = st.text_input("Your prompt:","What is in the picture?")


img_file_buffer  = st.camera_input("Take a picture")
    
if img_file_buffer is not None:
    
    # To read image file buffer as bytes:
    bytes_data = img_file_buffer .getvalue()
    
    # Convert bytes data to base64
    base64_encoded = base64.b64encode(bytes_data).decode()

    headers = {
      "Content-Type": "application/json",
      "Authorization": f"Bearer {api_key}"
    }

    payload = {
      "model": "gpt-4-turbo",
      "messages": [
        {
          "role": "user",
          "content": [
            {
              "type": "text",
              "text": title
            },
            {
              "type": "image_url",
              "image_url": {
                "url": f"data:image/jpeg;base64,{base64_encoded}"
              }
            }
          ]
        }
      ],
      "max_tokens": 300
    }

    response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)

    print(response.json())

    st.text(response.json())
