Why am I getting the "Backtest Error: Error initializing algorithm: This may be because history is using fake data while pre-analyzing an algorithm for a backtest" error? I am not using a warmup nor am I using FXCM data before 4/28/2007

I am getting the same error, and I am not using a warmup or FXCM data before 4/28/2007. Do you ever resolve this?

This error is likely in the Initialize method somewhere - without sharing a code snippet its hard to say why, If you'd like more assistance I'd recommend sharing a strategy.

Thanks for the response, Jared. Now, every algorithm I try to run just hangs on analyzing strategy, including this one copied exactly:
And this one:
class SomeAlgorithm(QCAlgorithm):
def Initialize(self):
pass
def OnData(self, slice):
pass

We have tested this algorithm and it has ended successfully:
25 | 08:14:59: Launching analysis for ~ with LEAN Engine v2.4.0.0.1492
26 | 08:21:47: Algorithm Id:(~) completed in 407.79 seconds at 5k data points per second.
Processing total of 1,902,880 data points.When we "pass" in Initialize method, the algorithm will make a simulation with default values. StartDate is Jan 1st 1998, EndDate is yesterday and benchmark is SPY. It is 1,902,880 data points that takes about 6:48 to be processed.
