Godot - System.Null Reference Exception

[vhalragnarok-ffxiv]

Following the directions, I install R3 from NuGet and add in the R3 Plugin, enable it in Project Settings, and am greeted with a minor error that doesn't seem to affect anything major yet.

" ERROR: /root/godot/modules/mono/glue/GodotSharp/GodotSharp/Core/NativeInterop/ExceptionUtils.cs:113 - System.NullReferenceException: Object reference not set to an instance of an object.

I am still able to use ReactiveProperties at least (TBH the main reason I use this library). I am unsure of what the cause is, I haven't studied the code that heavily beyond "Its not actually broken. Report it up, and continue with my life."

I can confirm I ran into this issue too. It breaks the observable tracker debugger which is a shame. I'm running godot v4.5.1 on windows. Likely due to some plugin API changes.
The core binding stuff works fine so a low priority bug, still would be nice to get a fix

Edit: Just noticed this is a duplicate of #334 with pr attempting to fix #332 but it doesn't work in 4.5.1:

  ERROR: modules\mono\managed_callable.cpp:96 - Parameter "delegate_handle.value" is null.
  ERROR: Can't get method on CallableCustom "Delegate::Invoke".
  ERROR: core\object\object.cpp:1310 - Error calling from signal 'started' to callable: 'ManagedCallableMiddleman::': Method not found.
  ERROR: ObservableTrackerDebuggerPlugin received message for unknown sessionId 0

Hi there! 👋 I've just submitted a solution in my PR #364.

Since I was working on the fix, I took the liberty of adding a few extra features that improve the workflow (like stack trace filtering and jump-to-source) ✨.

You should be able to resolve the issue by directly replacing the files with the ones in my PR. 🛠️
Quick tip: You might need to delete the old *.cs.uid files, rebuild, and toggle the plugin (disable/enable) to ensure a clean state.

Feel free to let me know if you spot any bugs! 🐛 I'm not sure if I'll have the time to fix them immediately, but I hope this helps! 🚀
