You called the function 'Value Selector' with these arguments: 1: String ("6683386" as String {encoding: "UTF-8", mediaType: "application/java; charset...) 2: Name ("Crop") But it expects one of these combinations: (Array, Name)

This is happening on a filter, with or without 'as String' on vars.shipmentId. I used as String to cast the variable to a string. $.ShipmentNumber is also a string.

<ee:set-payload><![CDATA[%dw 2.0

output application/json

---

{

shippedItemInstance: 

vars.ceresShipmentCSV filter $.ShipmentNumber == vars.shipmentId as String

map ( payload01 , indexOfPayload01 ) -> {

identifier: {

content: payload01.ShipmentNumber ++ "-" ++ payload01.SeqCode,

typeCode: "lineNumber"

},

vars.shipmentId is being set properly from a for each, as shown in the logs just prior to the DataWeave transform.

I have seen other unanswered Value Selector related forum posts.
