backfill_from issue with oandastore

Farout Al

Im trying to do a backfill from static data using "backfill_from" using oandastore as per code below:

dataBackfill = bt.feeds.PandasData(dataname=dataframe)            

data = oandastore.getdata(dataname=args.pair, backfill_from=dataBackfill,timeframe=bt.TimeFrame.Minutes, compression=1)

I get the following error when running:


  File "C:\ProgramData\Anaconda3\lib\site-packages\backtrader\feed.py", line 196, in _start_finish
    self._calendar = self._env._tradingcal

  File "C:\ProgramData\Anaconda3\lib\site-packages\backtrader\lineseries.py", line 461, in __getattr__
    return getattr(self.lines, name)

AttributeError: 'Lines_LineSeries_DataSeries_OHLC_OHLCDateTime_Abst' object has no attribute '_env'

Anyone have any idea what its complaining about?
"AttributeError: 'Lines_LineSeries_DataSeries_OHLC_OHLCDateTime_Abst' object has no attribute '_env'"

Let's assume you are using this: https://github.com/ftomassetti/backtrader-oandav20

You'd be better off posting in the project.

Thanks for the reply.
Im using Oanda v1 as per backtrader docs. Everything works in terms live data feed or adding static data from file or pandas but the backfill_from is giving me trouble.
In any case ill try to migrate to v20 and see if i get the same troubles.
