I’ve got Authorize attributes on my razor pages:

[Authorize(Roles = "Admin")]

And I’ve tried both of the below in Program.cs:

app.UseStatusCodePages(async context =>
{
    var response = context.HttpContext.Response;

    if (response.StatusCode == (int)HttpStatusCode.Forbidden)
    {
        response.Redirect("/Error/Unauthorized");
    }
});


app.Use(async (context, next) =>
{
    await next();

    if (context.Response.StatusCode == (int)HttpStatusCode.Forbidden)
    {
        context.Response.Redirect("/Error/Unauthorized");
    }
});

I placed a breakpoint on the status code checks and I noticed they are hit when loading the home page, but when I navigate to any other page they aren’t hit, no check is performed and while a 403 is returned, no redirection occurs and the user gets the browser’s default message about receiving a 403.

What am I missing to make the redirection occur?
