ReactiveStateEngine error " Can't find the corresponding reactive state function for sequence sensitive function isDuplicated "

Here is my code. I want to use isDuplicated with reactive state engine but it gives me an error "Can't find the corresponding reactive state function for sequence sensitive function isDuplicated"

Please help me.

temp1=table(100:0, `symbol`iif, [SYMBOL,DOUBLE])

rse1=createReactiveStateEngine(name="rse1",metrics=[<iif(isDuplicated([ts,symbol],LAST)=false,1,NULL)>],dummyTable=btc,outputTable=temp1,keyColumn=`symbol)

subscribeTable(tableName="btc", actionName="rse1", offset=0, handler=append!{rse1}, msgAsTable=true)
