OData actions with parameters not registering without ODataActionParameters as another parameter on the controller action

Hi there,

Using:
.NET 6
OData 8.0.5

Unless I am missing something, I am unable to get actions or functions with parameters to register properly unless I add an extra parameter to the controller action for ODataActionParameters.

To repro, clone the repo below and run:
https://github.com/joshcomley/ODataActionBug

For reference here is the EdmModel code:

public static IEdmModel GetEdmModel()
{
    if (_model != null)
    {
        return _model;
    }

    ODataConventionModelBuilder builder = new();
    
    var users = builder.EntitySet<User>("Users");

    // Works
    var hi = users.EntityType.Collection.Action(nameof(UsersController.Hi));
    hi.Returns<Hello>();

    // Doesn't work
    var hiSimpleFunction = users.EntityType.Collection.Function(nameof(UsersController.HiSimpleFunction));
    hiSimpleFunction.Returns<Hello>();
    hiSimpleFunction.Parameter<string>("name");

    // Doesn't work
    var hiSimple = users.EntityType.Collection.Action(nameof(UsersController.HiSimple));
    hiSimple.Returns<Hello>();
    hiSimple.Parameter<string>("name");

    // Doesn't work
    var hello = users.EntityType.Collection.Action(nameof(UsersController.Hello));
    hello.Returns<Hello>();
    hello.Parameter<SayHello>("request");

    // Doesn't work
    var goodbye = users.EntityType.Action(nameof(UsersController.Hello));
    goodbye.Returns<Hello>();
    goodbye.Parameter<SayHello>("request");

    return _model = builder.GetEdmModel();
}

And one of the actions that isn't working, for example:

[HttpPost]
public IActionResult HiSimpleFunction(string name)
{
    return Ok(
        new Hello
        {
            Message = $"Hi {name}!"
        }
    );
}
