Port type missmatch between blackborad and subtree port

[farshbafdoustar]

I have an ActionNode (Action1) that has input port with std::vector type:

<BehaviorTree ID="Main">
   <SubTree ID="Subtree_A" states="1;2"/>
  </BehaviorTree>

<BehaviorTree ID="Subtree_A">
    <Sequence>
        <Action1 states="{states}"/>
    </Sequence>
  </BehaviorTree>

When I want to pass sth to this port through a wrapper Subtree, I got the following error:

The creation of the tree failed because the port [states] was initially created with type [std::string] and, later type [std::vector<int, std::allocator<int> >] was used somewhere else.

it seems that the blackboard item defined in Main tree is created by default with std::string type. Is there anyway to define the type for the blackboard items in advance or any workaround to handle such a situation?
