I'm trying to write a plugin which could call Appian API which take CDT as parameter by using processDesignService.initiateProcess, referencing a library typetransformer-1.2.jar

I had the following exception(Log attached):
RROR com.appiancorp.suiteapi.common.TypedValueParameterConverter - unable to access property <value> in <class com.appiancorp.suiteapi.process.ProcessVariable>

Main logic Code :

//Appian CDT Type
                                        if (processInstanceType.intValue() >= 500) {
                                                  String cdtType = ts.getType(
                                                                      processVariable.getInstanceType()).getName();
                                                  String cdtNameSpace = ts.getType(
                                                                      processVariable.getInstanceType()).getNamespace();

                                                  System.out.println("cdtNameSpace: "
                                                                      + cdtNameSpace);
                                                  System.out.println("cdtType: "
                                                                      + cdtType);

                                                  Datatype type = ts.getTypeByQualifiedName(new QName(
                                                                       cdtNameSpace,cdtType));

                                                  AppianObject account = (AppianObject) tf.createElement(type
                                                                      .getId());
                                        ...

System.out.println("Process Parameters Length:"
                                                  + processParameters.length);

                              //ProcessStartConfig processStartConfig = getProcessStarterConfig(processParameters);
                              ProcessStartConfig processStartConfig = getProcessStarterConfig(new ProcessVariable[]{pvi});
                              processId = processDesignService.initiateProcess(modelId,
                                                  processStartConfig);

From the stack trace:

Caused by: java.lang.ClassCastException

It looks like you are making an invalid cast.
