Hi All,
I am encountering the following error with the default research notebook at line h1.loc["SPY"]["close"].plot():
AttributeError: '0, Culture=neutral, PublicKeyToken=null]]' object has no attribute 'loc'
Why is that happen and how to resolve it ? Thanks very much!

The reason why the error occurred is that when calling qb.History() there were no assets specified; the only parameters were the number of bars and the resolution.
The line should have been: h1 = qb.History(qb.Securities.Keys, 360, Resolution.Daily)
Since qb.Securities.Keys is called, all the securities added will be requested in this line.
Thanks Guru, that error was gone.
However, a new warning pop out:
