Eclipse Milo：写入对象成员变量

Question

当我将值写入变量（使用UaExpert）时，我从提供的ExampleServer中收到此错误，该变量是另一个对象的子级。我在引发异常的位置打印了访问级别，并且如您在下面的堆栈跟踪中看到的那样，似乎已删除CurrentWrite访问。有人可以帮忙吗？

变量配置：

UaVariableNode foo = UaVariableNode.builder(server.getNodeMap())
    .setNodeId(new NodeId(namespaceIndex, "ObjectTypes/MyObjectType.Foo"))
    .setAccessLevel(ubyte(AccessLevel.getMask(AccessLevel.READ_WRITE)))
    .setBrowseName(new QualifiedName(namespaceIndex, "Foo"))
    .setDisplayName(LocalizedText.english("Foo"))
    .setDataType(Identifiers.Int16)
    .setTypeDefinition(Identifiers.BaseDataVariableType)
    .build();

Stacktrace：

//  System.out.println(""+node.getDisplayName()+" "+accessLevels); prints:
LocalizedText{text=Foo, locale=en} [CurrentRead]
// Rest of the stack trace
