Hi,
I'm trying to download the S&P 500 constituents list for the year 2002 using the following code: 
sp2002, err = ek.get_data('.SPX(20020101)', 
                      'TR.IndexConstituentRIC'
                      )
the code was working before but is not working now; I get the "JSONDecodeError: Expecting value" error. 
I was wondering why this happens now, could anyone help me with this?
Thanks in advance,
Mahdieh
