AttributeError: 'NoneType' object has no attribute 'total_seconds' while using util.df

Hi guys,

Whenever I try using util.df to a BarData, I am receving the error below

AttributeError: 'NoneType' object has no attribute 'total_seconds'

Any idea about what could be the reason?

Thanks

I am using this workaround:

df = util.df(bars)
df["date"] = df["date"].dt.tz_convert("America/New_York")
print(df)

    It seems that the df does not know what timezone to use.

I edited function parseIBDatetime() in util.py file by adding t=pd.to_datetime(t.isoformat()) after string number 544. Now it works fine. The mistake appeared because of updates in Python 3.9
I found this solution in the internet, here:
