AWS Cognito & Flask app can't grab the jwt from the url

I have this simple Flask app, when you visit the landing page it redirects you to AWS Cognito portal where you login and then you get redirect to a webpage with a jwt in url. I am trying to get the jwt from the url but with no luck.

Everything works fine,

• I visit the app(localy)
• I get redirected to AWS Cognito portal
• I login & redirected to the flask app
• There I try to get the jwt but with no luck

Here's the code and what I've tried so far

from flask import Flask, render_template, redirect, request
app = Flask(__name__)

@app.route('/')
def landing_page():
    print('*' * 20)
    print(request.args)
    print(request.data.decode('UTF-8'))
    print(request.get_json())
    print(request.values)
    print(request.json)
    print(request.headers)
    print(request.headers.get('#id_token'))
    print(request.headers.get('id_token'))
    print(request.get_data().decode('UTF-8'))
    print(request.get_data())
    print(request.stream.read().decode('UTF-8'))
    print(request.args.get('id_token'))
    print(request.stream.read())
    print(request.args.to_dict([]))
    print(request.args.to_dict())
    print(request.args.get('id_token'))
    try:
        print(request.args['id_token'])
    except:
        print('pass')
    print('*' * 20)
    return redirect('https://xxx.auth.eu-central-1.amazoncognito.com/login?response_type=token&client_id=xxxxx&redirect_uri=http://localhost:5000/',
                    code=302)

And the results
