An exception when dictionary binding occurs

[AlexanderLapshin]

The package throws an exception when model has a property of type Dictionary<string, string>.

I have registered HybridModelBinding in startup:

services.AddMvcCore()
    .AddHybridModelBinder()
    .AddApiExplorer();

I have a controller that has one parameter with model

public async Task<IndexModelResponse> CreateIndex(IndexModelRequest command) =>
     await Mediator.Send(command);

I have a model with one property of type Dictionary<string, string>:

public class IndexModel
{
    public IDictionary<string, string> Name { get; set; }
}

If I make a request to this endpoint I have an exception:

System.ArgumentException: The value "[en, Automatic]" is not of type "System.String" and cannot be used in this generic collection. (Parameter 'value')

Request body:

{
    "Name": {
        "en": "Automatic"
    }
}

And additional question: Can I manually set by attribute when I want to HybridModelBinding, but not automatically when controller has a one parameter?

ASP.NET Core 3.1; SDK 3.1.405
Package version: 0.18.1 -alpha.4

I had tried to downgrade the package version to 0.18.0 and my output change to:

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
