hi, i noticed there is no error msg returned for get_historical_price_summaries, but instead a "None" is returned even you input an invalid ric. is there a way to turn on the error msg?
df = rdp.get_historical_price_summaries('XXX.XX', interval=rdp.Intervals.DAILY, start='2020.11.01', end='2020.11.06')
also what is the data limit for get_historical_price_summaries, looks it works for a short lookback windows, but not even more than a year. i.e., "None" is return when more than a year.
df = rdp.get_historical_price_summaries('IBM.N', interval=rdp.Intervals.DAILY, start='2019.11.01', end='2020.11.06')
