Hi All,

@SIOKEK YIM

This is a compile time error (a code level error inside class "StandardOPCUAService.java" line 320)

[ERROR] /kafkalog12/nifi/opc/nifi-opcua-bundle/nifi-opcua-bundle/nifi-opcua-service/src/main/java/com/hashmapinc/tempus/processors/StandardOPCUAService.java:[320,73]
 error: incompatible types: byte[] cannot be converted to ByteString 

.

Please check the line 320 of the "StandardOPCUAService.java" and verify if it is changed (OR) it might be possible that you might be building a different version of this git repo which might have a slightly different code for the mentioned line.

Unfortunately in the mentioned git repo link i do not see which exact tag / branch you are building so can not tell exactly where the code might have changed.

@Jay Kumar SenSharma

Thanks for replied. I’m using Apache Maven 3.2.1 & Java version: 1.8.0_101. I had changed pom.xml's system path version from opc-ua-stack-1.03.340.0-SNAPSHOT.jar to opc-ua-stack-1.03.342.1-SNAPSHOT.jar due to the OPCFoundation stack verison is /UA-Java/target/opc-ua-stack-1.03.342.1-SNAPSHOT.jar.

Seeing ed3766 posted (URL)

42721-capture.pngBut I think the changes had updated to the git repo and I had try copy & pasted the codes to StandardOPCUAService.java and same error occur.

Either I have to modify the codes or get the owner's answer about this issue but is there any alternative way to add opcua into NiFi as per mentioned here URL ?

Thanks for your support
