JSON Ошибка декодирования в python при использовании модуля запросов

base_url = "https://github.com/statsbomb/open-data/tree/master/data/"

comp_url =  base_url + "matches/{}/{}.json"
match_url = base_url + "events/{}.json"

Это ссылка, содержащая данные.

Я использовал функцию для анализа различных типов данных в ней 

def parsing_data(comp_id,season_id):
    matches = requests.get(url= comp_url.format(comp_id,season_id)).json()
    match_ids =  [m['match_id'] for m in matches]

    for id in match_ids:
        events = requests.get(url= match_url.format(id)).json()
        shots = [x for x in events if x['type']['name'] == 'Shot']

        all_events = []
        for s in shots:
            attribute = {
               'Match_ID' : id,
               'Team' : s['possession_team']['name'],
               'Player': s['player']['name'],
               'Minute': s['minute'],
               'X_shot': s['location'][0],
               'Y_shot': s['location'][1],
               'Shot_with': s['body_part']['name'],
               'Outcome': s['outcome']['name']
            }
            all_events.append(attribute)

    return pd.DataFrame(all_events)

Но я получаю JSONDecodeError: Ожидаемое значение: строка 6, столбец 1 (char 5) l ie this, когда я вызываю функцию, 

comp_id = 43
season_id = 3

df = parsing_data(comp_id,season_id)

Может ли кто-нибудь помочь мне с этим?

Вы перешли по ссылке GitHub, вам нужно взять ссылку на исходные данные файла GitHub, например

https://raw.githubusercontent.com/statsbomb/open-data/master/data/

И другое дело, вы должны использовать requests.get(url="").content для извлечения данных.
И еще одно - это данные body_part & результат находятся в shot .

Его можно преобразовать в объект JSON с помощью json.loads(string)

Затем вы можете написать код как 

import requests
import pandas as pd
import json

base_url = "https://raw.githubusercontent.com/statsbomb/open-data/master/data/"

comp_url =  base_url + "matches/{}/{}.json"
match_url = base_url + "events/{}.json"

def parsing_data(comp_id,season_id):
    matches = json.loads(requests.get(url=comp_url.format(comp_id,season_id)).content)
    match_ids =  [m['match_id'] for m in matches]

    for id in match_ids:
        events = requests.get(url= match_url.format(id)).json()
        shots = [x for x in events if x['type']['name'] == 'Shot']

        all_events = []
        for s in shots:
            attribute = {
               'Match_ID' : id,
               'Team' : s['possession_team']['name'],
               'Player': s['player']['name'],
               'Minute': s['minute'],
               'X_shot': s['location'][0],
               'Y_shot': s['location'][1],
               'Shot_with': s['body_part']['name'],
               'Outcome': s['outcome']['name']
            }
            all_events.append(attribute)

    # return pd.DataFrame(all_events)

comp_id = 43
season_id = 3

df = parsing_data(comp_id,season_id)

Спасибо

base_url необходимо изменить, чтобы получить необработанный контент Json, также были две ошибки в Shot_with и Outcome.

Этот скрипт: 

import requests
import pandas as pd


# changed the base_url to get raw content:
base_url = "https://raw.githubusercontent.com/statsbomb/open-data/master/data/"

comp_url =  base_url + "matches/{}/{}.json"
match_url = base_url + "events/{}.json"

def parsing_data(comp_id,season_id):
    url = comp_url.format(comp_id,season_id)
    matches = requests.get(url=url).json()
    match_ids =  [m['match_id'] for m in matches]

    for id in match_ids:
        events = requests.get(url= match_url.format(id)).json()
        shots = [x for x in events if x['type']['name'] == 'Shot']

        all_events = []
        for s in shots:
            attribute = {
               'Match_ID' : id,
               'Team' : s['possession_team']['name'],
               'Player': s['player']['name'],
               'Minute': s['minute'],
               'X_shot': s['location'][0],
               'Y_shot': s['location'][1],
               'Shot_with': s['shot']['body_part']['name'], # <-- added 'shot'
               'Outcome': s['shot']['outcome']['name']      # <-- added 'shot'
            }
            all_events.append(attribute)

    return pd.DataFrame(all_events)

comp_id = 43
season_id = 3

df = parsing_data(comp_id,season_id)
print(df)
