Hello,

I am trying to use federal funds rate data in my algo. I have been folloeing FRED docs here 

Here is sample code (can't attach backtest because of error):

# region imports
from AlgorithmImports import *
# endregion

class SquareYellowGreenCaterpillar(QCAlgorithm):

    def Initialize(self):
        self.SetStartDate(2021, 4, 13)  # Set Start Date
        self.SetCash(100000)  # Set Strategy Cash
        self.ir = self.AddData(Fred, Fred.CommercialPaper.CPFF, Resolution.Daily).Symbol

        # Historical data
        history = self.History(self.ir, 60, Resolution.Daily)
        self.Debug(f"We got {len(history)} items from our history request")

    def OnData(self, data: Slice):
        if slice.ContainsKey(self.fred_peak_to_trough):
            ir = slice.Get(Fred, self.ir).Value

This simple script returns an error:

[ERROR] FATAL UNHANDLED EXCEPTION:Engine.Run(): During the algorithm initialization, the following exception has occurred: type object 'CommercialPaper' has no attribute 'CPFF',  at Initialize,    self.ir = self.AddData(Fred in main.py: line 9, type object 'CommercialPaper' has no attribute 'CPFF',ApiConnection.TryRequest(backtest/status/update): Error: The operation has timed out.
