.NET Core RedirectToAction causes InvalidOperationException Error

Question

I have a page located in:

An Area called Action
A Controller called Message
A Method called Index

When I log into my application, I go to the HomeController which then redirects me like this:

public IActionResult Index()
{
    return RedirectToAction("Index", "Messages", new { area = "Action" });
}

However, I get this error:

An unhandled exception occurred while processing the request. InvalidOperationException: No route matches the supplied values. Microsoft.AspNetCore.Mvc.Infrastructure.RedirectToActionResultExecutor.ExecuteAsync(ActionContext context, RedirectToActionResult result)

Its very long but I found that it has something to do with my last await.next() line in my Startup.cs:

app.Use(async (context, next) =>
{
    if (context.Response.StatusCode == 404 && !context.Response.HasStarted)
    {
        string originalPath = context.Request.Path.Value;
        context.Items["originalPath"] = originalPath;
        context.Request.Path = "/Error/404";
        await next();
    }
    if (context.Response.StatusCode == 401 && !context.Response.HasStarted)
    {
        string originalPath = context.Request.Path.Value;
        context.Items["originalPath"] = originalPath;
        context.Request.Path = "/Error/401";
        await next();
    }

    if (context.Response.StatusCode == 302 && !context.Response.HasStarted && context.User.Identity.IsAuthenticated)
    {
        string originalPath = context.Request.Path.Value;
        context.Items["originalPath"] = originalPath;
        context.Request.Path = "/Error/302";
        await next();
    }
    if (context.Response.StatusCode == 400 && !context.Response.HasStarted)
    {
        string originalPath = context.Request.Path.Value;
        context.Items["originalPath"] = originalPath;
        context.Request.Path = "/Error/400";
        await next();
    }
    await next();
});

This is my routing in Startup.cs also:

app.UseMvc(routes =>
{
    routes.MapRoute(
      name: "areas",
      template: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
    );
    routes.MapRoute(
        name: "default",
        template: "{controller=Home}/{action=Index}/{id?}");

});

I have this exact Startup.cs in other applications and they run just fine. Not sure whats wrong with this one?

EDIT:

The full exception:

EDIT 2:

When I removed the redirecttoaction and replaced it with a return Page(); The page loads. That means that the area redirection isn't working?

it is a typo for controller Message and in route Messages ?? — Mangesh Auti
I tried another controller and its all the same. Something is wrong with my Startup I guess? — JianYA
here you mention return RedirectToAction("Index", "Messages", new { area = "Action" }); "Messages" and in que description Controller called "Message" extra s is it typo error? — Mangesh Auti

Use only one route. Try like below:-

routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            namespaces:new[] {"MVCDemo.Controllers"}
        );
