Getting class cast exception

[vaithu]

I'm getting this error

Exception in thread "main" java.lang.ClassCastException: class com.google.gson.internal.LinkedTreeMap cannot be cast to class com.holonplatform.core.property.PropertyBox (com.google.gson.internal.LinkedTreeMap and com.holonplatform.core.property.PropertyBox are in unnamed module of loader 'app')

and my code is

ListPathProperty<PropertyBox> DASAENTRIES = ListPathProperty.propertyBox("dasaEntries",DasaEntries.PROPERTIES);
    PropertySet<?> PROPERTIES = PropertySet.builderOf(DASAENTRIES)
            .build();
    PathProperty<PropertyBox> VIMSHOTTARIDASA = PathProperty.create("vimshottariDasa", PropertyBox.class)
            .withConfiguration(PropertySet.PROPERTY_CONFIGURATION_ATTRIBUTE,PROPERTIES)

            ;


List<PropertyBox> dasaEntriesBox = propertyBox.getValue(VimshottariDasa.DASAENTRIES);

            for (PropertyBox pb : dasaEntriesBox) {
                System.out.println(pb);
            }

The error gets popup when I use this line

for (PropertyBox pb : dasaEntriesBox) {
                System.out.println(pb);
            }

Please help me to resolve this error.
