}, {
"name" : "ErrorList",
"type" : {
"type" : "array",

},
"doc" : "Type inferred from '[]'"
} ]
}And the Query i use is;
select (ResultList, '/Index') as "index", (ResultList, '/Sentiment') as "sentiment", (ResultList, max('/SentimentScore')) as "score" from FLOWFILEWhile Executing i get the following Error,
Can someone help me achieving this use case?
