Error with JSON? How to decide?

Question

Python

There is a code:

import requests
import json




#1 Приём сообщений
#2 Отсылка сообщений



URL = 'https://api.telegram.org/botтокен скрыт/'





def write_json(data, filename='answer.json'):
    with open(filename, 'w') as f:
        json.dump(data, f, indent=2, ensure_ascii=False)
        
def get_updates():
    url = URL + 'getUpdates'
    r = requests.get(url)
    write_json(r.json)

def main():
    get_updates()





if __name__ == '__main__':
    main()

When I run it on windows I get the following error:

Traceback (most recent call last):

    raise TypeError(f'Object of type {o.__class__.__name__} '
TypeError: Object of type method is not JSON serializable

What to do?
