Closing/re-opening project ScriptableGraphModel.asset not found

[akatriel]

Produced in Unity 2023.2.3.16f1 Upon closing and re-opening project the AssetDatabase appears to lose the reference to the ScriptableGraphModel.asset with the following error:

settings blueprint could not be resolved! Path: Assets/Scripts/Editor/NewGraph/Editor/Settings/GraphSettings.asset GUID: 015778251503b3c44a2b9dfc3a36ad10 UnityEngine.Debug:LogError (object) NewGraph.GraphSettingsSingleton:get_BlueprintSettings () (at Assets/Scripts/Editor/NewGraph/Editor/Settings/GraphSettingsSingleton.cs:34) NewGraph.GraphSettingsSingleton:get_Settings () (at Assets/Scripts/Editor/NewGraph/Editor/Settings/GraphSettingsSingleton.cs:55) NewGraph.GraphWindow:InitializeWindowBase (System.Type) (at Assets/Scripts/Editor/NewGraph/Editor/Views/GraphWindow.cs:80) WindowInitializer.WindowInitializer:OpenWindow () (at Assets/Scripts/Editor/JobClassGraph/WindowInitializer.cs:12)

WindowInitializer was moved out of the Sample folder to a Scripts > Editor folder but has been unchanged:

namespace WindowInitializer {
    public class WindowInitializer {
        /// <summary>
        /// Here you can customize where the graph window menu should appear
        /// </summary>
        [MenuItem("Tools/" + nameof(GraphWindow))]
        static void OpenWindow() {
            // Here you can define what type of graph model you would like to use.
            GraphWindow.InitializeWindowBase(typeof(ScriptableGraphModel));
        }
    }
}

Any help appreciated!

Did you install NewGraph as a package or did you clone it locally? Sadly, there is a Unity bug the results in broken references when using git repos as packages. :/

OdinSerializer was installed as a package, however, GraphViewBase and New Graph were cloned locally into Assets > Scripts > Editor.

Hey, New Graph has a runtime and an Editor portion so it needs to sit directly in the Assets Folder or insides a Plugins folder, so maybe that is part of the problem 🙂

Unfortunately, the error still exists even after completely removing it from the project and then re-copying the libraries to the Assets folder.

I think the WindowInitializer.asmdef was the issue here. In my project preferences under External Tools > 'Generate .csproj files for:' > 'Embedded Packages' and 'Local Packages' are both checked. After copying the WindowInitializer to Assets>Scripts>Editor folder and deleting the .asmdef everything seems to work. Not sure why this would be related, but also not questioning this anymore...
