We are faicng error while using EMA Code : error: type mismatch. Please assist

Hi,

We are using Scala. The code we are referring is mentioned here

https://developers.refinitiv.com/article/get-real-time-market-data-using-ema-java-scala-language

As mentioned, decode(fieldList: FieldList) is failing with given error.

We are running this in scala interpreter and trying to run forEach loop to extract each single field and use it for further purpose.

class AppClient extends OmmConsumerClient {

def onRefreshMsg(refreshMsg: RefreshMsg,event: OmmConsumerEvent) {

println("Refresh Message of: " +

(if (refreshMsg.hasName()) refreshMsg.name()

else "<not set>"))

println("Service Name: " +

(if (refreshMsg.hasServiceName()) refreshMsg.serviceName()

else "<not set>"))

println("Item State: " + refreshMsg.state());

//println(refreshMsg)

val a = refreshMsg.payload().fieldList().size

println(a)

decode(refreshMsg.payload().fieldList())

}

def decode(fieldList: FieldList){

fieldList.forEach((fieldEntry:FieldEntry) => {

print("\tFid: " + fieldEntry.fieldId() + " Name: " + fieldEntry.name() + " DataType: " + DataType.asString(fieldEntry.load().dataType()) + " Value: ")

})

}

def onUpdateMsg(updateMsg: UpdateMsg,event: OmmConsumerEvent) {

println("Update Message of: " +

(if (updateMsg.hasName()) updateMsg.name()

else "<not set>"))

println("Service Name: " +

(if (updateMsg.hasServiceName()) updateMsg.serviceName()

else "<not set>"))

println(updateMsg)

}

def onStatusMsg(statusMsg: StatusMsg,event: OmmConsumerEvent) {

println("Status Message of:" +

(if (statusMsg.hasName()) statusMsg.name()

else "<not set>"))

println("Service Name: " +

(if (statusMsg.hasServiceName()) statusMsg.serviceName()

else "<not set>"))

if (statusMsg.hasState())

println("Item State: " + statusMsg.state())

println()

}

def onGenericMsg(genericMsg: GenericMsg,event: OmmConsumerEvent) { }

def onAckMsg(ackMsg: AckMsg,event: OmmConsumerEvent) { }

}
