I'm trying to parse the information found in this link here: http://stats.nba.com/stats/playergamelog?DateFrom=&DateTo=&LeagueID=00&PlayerID=203518&Season=2016-17&SeasonType=Pre+Season
What I want to pull is the information under rowSet (so 0, 1, 2, etc will be one entry) 
Code I'm using:
import requests
urlPlayerLog = "http://stats.nba.com/stats/playergamelog?DateFrom=&DateTo=&LeagueID=00&PlayerID=203518&Season=2016-17&SeasonType=Pre+Season"
responses = requests.get(urlPlayerLog)
dataGameLogs = responses.json()['resultSets'][0]['rowSet']
This was working for me for months and then one day I kept getting the following error:

Which made me think the issue was with dataGameLogs = responses.json()['resultSets'][0]['rowSet'] , but unsure why that is returning an error...
responses.textto see if you got anything before proceeding.
