How to rectify the Error While trying to use a!save on an array type : Only fields with scalar types can be indexed from an array.

A Score Level 1

Hi All,

Need to manipulate a complex JSON from external Integration in Appian Interface, so using a Multiple CDT Structure which internally can contain multiple CDTs.

Sample Structure : 

{

{

key1:value1,

key2:{key3:value3,key4:value4},

key5:value5

},

{

key1:xx,

key2:{key3:yy,key4:zz},

key5:aa

}

}

I am unable to use a!save to store multiple array-type, giving Error:Only fields with scalar types can be indexed from an array.

I am trying to save data like this :

a!save(target:ri!data,
value:
{
dataId:local!termCode,
formulationId:null,
dataName:local!termName,
otherDataName:local!otherName
})

Process Model is not used, from interface, directly passing the cdt  to another Integration, converting to JSON as we are using External DB.

An error occurred while executing a save: java.lang.IllegalArgumentException: Cannot index "dataDetails" because it is an array type (List of CTD_Data). Only fields with scalar types can be indexed from an array.

Please Let me know how to handle this.
