I have a process Id in my plugin, How to read the PV of type CDT of that process instance using API?

I have used the below code to fetch the CDT, But it is returning me an object. But the expectation is to fetch the CDT(of type multiple) values.

ServiceContext sc = WebServiceContextFactory.getServiceContext(req);
ProcessExecutionService pes = ServiceLocator.getProcessExecutionService(sc);
ProcessVariableInstance pv1 = pes.getProcessVariable(processId, "PVName");
System.out.println("PV1 name: " + pv1.getName() + " Value: " + pv1.getRunningValue());
-------------------
Output
-------------------
PV1 name: PVName Value: [[Ljava.lang.Object;@6502ee80

Any suggestions ?

The Type Transformer library can help read CDTs in Java. It can be downloaded from shared components and has examples in the Java docs.

To get CDT values as a string you need to do the following..
TypeService ts=ServiceLocator.getTypeService(context);
AppianTypeFactory tf= AppianTypeFactory.newInstance(ts);
AppianElement ae=tf.toAppianElement(pv1);
return ae.toString();
