I have a Web Application that uses Flask that was working right only it is now returning me an error.

The application does a search in the name of the players in a json file, in the execution of the for that is in index.html I am getting the following error:

Typeerror: 'Nonetype' argument is not iterable

main py.

from flask import Flask, render_template
import requests
import json


app = Flask(__name__)

def get_json(url):
    return json.loads(requests.get(url).text)


flight = get_json('http://infinite-flight-public-api.cloudapp.net/v1/Flights.aspx?'
            'apikey=78879b1d-3ba3-47de-8e50-162f35dc6e04&sessionid=7e5dcd44-1fb5-49cc-bc2c-a9aab1f6a856')

@app.route('/')
def index():    
    return render_template('index.html', data=flight)

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

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
    <table>
        <thead>
            <tr>
                <th>Nome</th>
            </tr>
        </thead>
        <tbody>
            {% for data in data %}
                {% if 'IFAB' in data['DisplayName'] %}
                <td>{{data['DisplayName']}}</td>
                {% endif %}
            {% endfor %}
        </tbody>
    </table>

This is happening because the code is searching for null values. You can try to delete these null values or remove them from the search. Ex.:

   <tbody>
        {% for data in data %}
            {% if data['DisplayName'] is not None %}
                {% if 'IFAB' in data['DisplayName'] %}
                   <td>{{data['DisplayName']}}</td>
                {% endif %}
            {% endif %}
        {% endfor %}
   </tbody>
