`logic_error` on `BT::BehaviorTreeFactory::registerNodeType()` When Setting `InputPort` `default_value` to `nullptr` After Commit 789ce6ea0ad3627923bd2389b8fb9199ffab6d84 about behaviortree.cpp HOT 5 CLOSED

Please provide a unit test. Also what is the type of the port?
What is your intent with a nullptr?

from behaviortree.cpp.

Thank you for your prompt reply.

I cannot provide a unit test right away, but I will first address the latter part of your question.

I had set nullptr as the default value for shared_ptr as shown below. T is a class with a high instantiation cost, and an instance is only created within the Node if it's nullptr. Is this usage unexpected?

    static BT::PortsList providedPorts()
    {
        return {
            BT::InputPort<std::shared_ptr<T>>("test", nullptr, "description")};
    };

Ok, let me have a look

from behaviortree.cpp.

Check 83fce13

If the problem persists, please tell me how to extend the unit test Default_Issues_767_768 to cover your case.

from behaviortree.cpp.
