It means that by:

$(varMinDate) + Iterno()-1 As Num

the variable $(varMinDate) has no valid value else is NULL. This might be caused from your INVOICE_DATE which might be not interpreted numeric else as a string which would affect your min/max aggregation as well as the num() wrapping of the peek().

Another cause could be that INVOICE_DATE isn't a date else a timestamp. In this case the value has a decimal-delimiter and if the delimiter is a comma the variable would interpret it as delimiter for the variable itself and not for the value and again the result would be NULL.
