Using Django Deployment

I keep getting this Server 500 error while deploying my to Heroku. It runs perfectly on my Local host. The other page on the site works fine but this one has the News-API. Not sure what to do next.

CODE

from django.shortcuts import render
import requests
import os
from dotenv import load_dotenv, dotenv_values
from newsapi import NewsApiClient

load_dotenv()
API = os.getenv('NEWS_API')

def index(request):
    url = (f"https://newsapi.org/v2/everything?q=gaming&apiKey={API}")
    gaming_news = requests.get(url).json()
    a = gaming_news['articles']

    urlToImage = []
    author = []
    title = []
    description = []
    url = []

    for i in range(len(a)):
        f = a[i]
        urlToImage.append(f['urlToImage'])
        author.append(f['author'])
        title.append(f['title'])
        description.append(f['description'])
        url.append(f['url'])
    news_list = zip(urlToImage, author, title, description, url)
    
    context = {'news_list': news_list}

    return render(request, 'news/news.html', context)

I tried change up the code but I’ve been at it way too long already.

This error indicates that the key ‘articles’ doesn’t exist in the response JSON returned by the News API. May be an issue with your API key or incorrect URL construction, or a problem with the API itself. use try and except to identify the main issue.
