Hello, I hate for this to be my first post here haha.

But I'm a newb and I ran into an issue with the Tiingo bootcamp that I'm trying to solve. I finally just pressed “Solution” and it still won't process without this error, so I think something must have changed on the backend. Here is the solution code and the error I'm getting.

Thank you in advance!

#1. Import Tiingo Data 
from QuantConnect.Data.Custom.Tiingo import *
from datetime import datetime, timedelta
import numpy as np

class TiingoNewsSentimentAlgorithm(QCAlgorithm):

def Initialize(self):
self.SetStartDate(2016, 11, 1)
self.SetEndDate(2017, 3, 1)

#2. Add AAPL and NKE symbols to a Manual Universe
symbols = [Symbol.Create("AAPL", SecurityType.Equity, Market.USA),
Symbol.Create("NKE", SecurityType.Equity, Market.USA)]

# 3. Add an instance of the NewsSentimentAlphaModel


# 4. Create a NewsSentimentAlphaModel class with Update() and OnSecuritiesChanged() methods
class NewsSentimentAlphaModel(AlphaModel):
def __init__(self):
def Update(self, algorithm, data):
insights = []
return insights
def OnSecuritiesChanged(self, algorithm, changes):

and here is the error I get:

Runtime Error: Object reference not set to an instance of an object. in AlphaModelPythonWrapper.cs:line 84	 (Open Stacktrace)
