Error on Quantopian resulting from using a for loop to transverse a universe of securites made with pipeline

LinAlgError: Array must not contain infs or NaNs
There was a runtime error on line 102.

I am running a loop across a list of securities i have made using a q1500US pipeline and i use data.history to get the daily price for a window of 120 days and do some calculation during that timeframe.Does anyone know what that error code could mean about my dataset. During this calculations i try to fit a polynomial to my data set and extract some basic features from the resulting calculations.

It sounds like the bug could be anywhere between the actual computations being done in pipeline to the access of the output later on in the code. It's tough to help debug without seeing the code. Would you be willing to share your algorithm by attaching it as a notebook or backtest to this post? If you don't want to publicize the code, your best bet is to share it with our support team by using the Help >> Contact Support modal and giving them permission to look at the code.
