Agg function error

[rrdvg]

I am trying to do sum aggregate CY = current year sales by date

It says data type is string I tried converting it to int as well, did not work

df_group = df.groupby(df.Reporting_Date, agg=vaex.agg.sum(df.CY))
df_group

Getting below error
AttributeError: type object 'str' has no attribute 'kind'

Any help appreciated
