Need Help with Flask Integration for OpenAI API

API
1

Hello, I’m trying to create a Flask application that interacts with the OpenAI API for chat completions. However, I’m encountering an error message: “An error occurred while fetching the response.” Below is my code

import os
from openai import OpenAI, OpenAIError
from dotenv import load_dotenv
from flask import Flask, request, jsonify, render_template

load_dotenv()
api_key = os.getenv('OPENAI_API_KEY')
client = OpenAI(api_key=api_key)

app = Flask(__name__)

@app.route("/")
def index():
    return render_template("index.html")

@app.route('/chat', methods=['POST'])
def chat():
    try:
        data = request.get_json()
        user_input = data.get('message')

        if not user_input:
            return jsonify({'error': 'No message provided'}), 400

        response = client.chat.completions.create(
            model="gpt-4",
            messages=[{
                "role": "user",
                "content": user_input
            }],
            max_tokens=150
        )

        return jsonify({'response': response.choices[0].message['content']})

    except OpenAIError as e:
        return jsonify({'error': str(e)}), 500

    except Exception as e:
        return jsonify({'error': 'An unexpected error occurred'}), 500

if __name__ == '__main__':
    app.run(debug=True)

Error Message:

An error occurred while fetching the response.

Steps Taken:

  1. Verified API key is correctly loaded from the .env file.
  2. Ensured Flask and other dependencies are installed and up to date.
  3. Checked for any indentation or syntax issues.

Can anyone help me identify what might be causing this issue? Thank you!

Hey there ! for the code above the method changed, try using response.choices[0].message.content and not [‘content’]

Thanks ytyt but your proposal does not seem to work. Here is what ChatGPT replied:

“In the context of working with OpenAI’s API, when handling responses from the API, the correct syntax is to use the dictionary access method, which is response.choices[0].message['content'] …
If the structure was different and message was an object with attributes, then response.choices[0].message.content could be correct. However, in OpenAI’s API, message is a dictionary, so you need to use the dictionary access method.”

Any other suggestions would be most welcome!

Chatgpt has outdated information doc information after the big library update. Try referring to platform.openai.com for the example scripts and API reference.
