Odd error

[americanslon]

Good day, I have a very strange error I was hoping you can help with. I am not sure it's a bug so I figured I won't pollute "Issues" and put it here.

What I am trying to do here is set a MudBlazor (blazor UI controls library) theme state using BlazorState to have it available in other parts of the application.

Some code - ThemseState defenition

  public partial class ThemeState : State<ThemeState>
    {
        public MudTheme Theme { get; private set; }
        public override void Initialize() => Theme = null;
    }

 public partial class ThemeState
      {
          public class SetThemeHandler : ActionHandler<SetThemeAction>
          {
              public SetThemeHandler(IStore aStore) : base(aStore) { }
  
              ThemeState state => Store.GetState<ThemeState>();
  
              public override Task<Unit> Handle(SetThemeAction action, CancellationToken aCancellationToken)
              {
                  state.Theme = action.Theme;
                  return Unit.Task;
              }
          }
      }

    public partial class ThemeState
    {
        public class SetThemeAction : IAction
        {
            public MudTheme Theme { get; set; }
        }
    }

//theme definition class
public class Blue : MudTheme
    {
        public Blue()
        {
            LayoutProperties.DrawerWidthLeft = "270px";
            LayoutProperties.DefaultBorderRadius = "2px";
            ZIndex.AppBar = 1;   

            Palette = new Palette()
            {
                Primary = "#1e597a",
                Secondary = "#5d8880",
                Tertiary = "#ffffff",
                DrawerIcon = "#ffffff",
                Background = "#F7F7F8",
                BackgroundGrey = "#F7F7F8",
                Error = "#8e1c38",
                Success = "#89ab7e",
            };
        }
    }

Now when I try to set the state await Mediator.Send(new ThemeState.SetThemeAction { Theme = new Blue()}); I get an error

EDIT: I noticed that this happens on the second await Mediator.Send call. The first one works fine but updateting the state for the second time gets the below error.

To make matters stranger this only happens in prod (azure app service). Locally, I don't get the error.
Sorry to throw these walls of text at you but I am at a loss on where to even begin here.

I am including a text file with all the above code, it's a bit more readable there. new 1.txt

Thanks for your help!

It looks like an error when trying to clone the MudTheme object.

I am going to guess at your scenario here so I apologize if I am wrong.

I am assuming you want to support 2 themes, Dark and Light. And both of these Themes are constants and never change, just the user switches back and forth.

If that is the case I wouldn't even store the MudTheme itself in the store. Instead store an enum Dark/Light. Then use this enum to select your MudTheme from a const array/list.

If the MudTheme isn't const and you do need it in the store and AnyClone can't clone it (the error you are seeing) then you will have to write you own clone method and implement ICloneable.

Something like that, yeah. I do need individual theme object in the store because a bunch of components read properties from it. It's also not a constant (as far as I can tell)

What would make an object not clonable?
The interesting thing is that this started happening with one of MudBlazor's recent updates (v6.0.10->v6.0.11) and I have been looking at the source code for their theming and there doesn't seem to be anything changed at all in months...
