Hello and sorry for the late reply.
I have recently re-uploaded the FlowCanvas-NodeCanvas bridge unitypackage.
Please download and use the new updated version.
Graph.agent and Graph.blackboard should really stay private due to changes made in latest version 🙂
Thanks!
(PS: There was an ongoing issue with the hosting service provided within the last few days that result in the website being very slow. I am sorry about that.).
