ValueError: cannot reshape array of size 0 into shape (0)

[BlackPearl]

Hello

I am building a strategy using ensemble learning using voting classifier, however when running precheck 1/3, the error ValueError: cannot reshape array of size 0 into shape (0) occurs. I tried using stock codes listed on the stock exchange before 2006 (AAPL, AMZN, MSFT) but still got the above error. Please help me.

My strategy ID is 16819018



Thank you so much
