Is it possible to perform group by and sum operation in Mapper/Conditional snap?

[nirupama]

Is it possible to perform sum of the values by grouping them on few fields in mapper/conditional snap in snaplogic.
Because with aggregate snap I’m losing all input fields and keeping copy snap is taking more time to execute.

Does it mean that your input is plain array literal and not an object array?

The error you’re receiving is telling you that the instance of “curr” - current is a BigDecimal. Can you provide a sample payload here?
