cerebro.resampledata() failure

[quachbq]

The following call to backtrader.Cerebro.resampledata() failed, which works with the original Backtrader:

data_hour = cerebro.resampledata(
    dataname=data,
    name='hour',
    timeframe=bt.TimeFrame.Minutes,
    compression=60,  # 60 minutes = 1 hour
    bar2edge=True
)

ERROR:
