Morningstar is now discontinued per: https://github.com/pydata/pandas-datareader/issues/557 You can still go to Morningstar's site and sign up for API access, but pandas_datareader has no input I can see for a Morningstar...

'iex' works if you change the column names to use lower case and the 'Adj close' to 'close'.
