Traceback error when I am attempting to grab all box scores

headers  = {

from nba_api.stats.endpoints import leaguegamefinder

# get game logs from the reg season
gamefinder = leaguegamefinder.LeagueGameFinder(season_nullable='2020-21',
                                               league_id_nullable='00',
                                               season_type_nullable='Regular Season')
games = gamefinder.get_data_frames()[0]

# get a list of distinct game ids
game_id = games['GAME_ID'].unique().tolist()

player_stats_data = boxscoreadvancedv2.BoxScoreAdvancedV2(game_id=game_id, headers=headers, timeout=100)
stats_df = player_stats_data.get_data_frames()[0]
stats_df.head()

I get error JSONDecodeError: Expecting value: line 1 column 1 (char 0) error.

I believe it has something to do with my game id's being in a list ? Because when I run a specfic game id number, so:

player_stats_data = boxscoreadvancedv2.BoxScoreAdvancedV2(game_id='000127338', headers=headers, timeout=100)
    stats_df = player_stats_data.get_data_frames()[0]
    stats_df.head()

It returns the data from that game.

Why is it not reading all game id's in the list though?

EDIT:

**Here is the for loop I have created after receiving an answer. This for loop has solved my issue. **

for game_id in game_ids:
    player_stats_data = boxscoreadvancedv2.BoxScoreAdvancedV2(game_id=game_id, headers=headers, timeout=100)
    time.sleep(.600)
    df = player_stats_data.player_stats.get_data_frame()
    df['GAME_ID'] = game_id
    print(game_id)
    boxscores.append(df)

Answer 1

Looking at the API documentation, it takes a single game id.

One approach could be to loop over the game ids you have:

game_ids = games['GAME_ID'].unique().tolist()
for game_id in game_ids:
    player_stats_data = boxscoreadvancedv2.BoxScoreAdvancedV2(game_id=game_id, headers=headers, timeout=100)
    # Use the stats...
