Reply To: "Type with name could not be resolved" for classes that definitely exist

I did the full upgrade to 3.0.8, and the errors went away! This reveals another issue I didn’t notice before, but was definitely there:

1 2 3 4 5 6 7

NullReferenceException: Object reference not set to an instance of an object at NodeCanvas.Framework.Graph.UpdateNodeBBFields () [0x00023] in /Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/Graph.cs:415 at NodeCanvas.Framework.Graph.UpdateReferences (UnityEngine.Component newAgent, NodeCanvas.Framework.IBlackboard newParentBlackboard, System.Boolean force) [0x00080] in /Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/Graph.cs:408 at NodeCanvas.Framework.Graph.UpdateReferencesFromOwner (NodeCanvas.Framework.GraphOwner owner, System.Boolean force) [0x00001] in /Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/Graph.cs:391 at NodeCanvas.Framework.GraphOwner.Validate () [0x000c2] in /Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/GraphOwner.cs:469 at NodeCanvas.Framework.GraphOwner.OnValidate () [0x00001] in /Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/GraphOwner.cs:450 (Filename: Assets/ParadoxNotion/CanvasCore/Framework/Runtime/Graphs/Graph.cs Line: 415)

…this is a build error, not a runtime error. There is one of these for each of our BT assets. That particular line is trying to access allParameters.

I don’t know at this stage if this is having any material affect on the builds, but I’d rather figure out why it’s happening than slap a nullref check around it. Since it doesn’t happen to us in the editor that often, allParameters is obviously _mostly_ non-null.
