ASP.NET Core 6: Custom Authorization Policy Not Triggering in Controller despite Proper Setup

I'm working on a personal project and I tried several approaches but none seem to work... I'm working on a personal project and I'm currently working with ASP.NET Core 6 and have set up a custom authorization policy that I expect to be triggered in my controller, but it doesn't seem to activate as anticipated. I've configured the policy in `Startup.cs` like this: ```csharp services.AddAuthorization(options => { options.AddPolicy("RequireAdministratorRole", policy => policy.RequireRole("Admin")); }); ``` In my controller, I applied the policy with the `[Authorize]` attribute: ```csharp [Authorize(Policy = "RequireAdministratorRole")] public class AdminController : ControllerBase { public IActionResult Index() { return Ok("You are an admin!"); } } ``` When I test it with a user who has the "Admin" role, I still receive a 403 Forbidden response. I've verified that the user is correctly authenticated and holds the role by checking it directly in the application database. I've also made sure to call `app.UseAuthentication();` and `app.UseAuthorization();` in the correct order in the `Configure` method: ```csharp public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseRouting(); app.UseAuthentication(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } ``` Despite all this, the policy doesn't seem to trigger. I've even tried adding logging to see if the authorization process is hitting the expected checks, but it doesn’t appear to be evaluating the policy. Any thoughts on what might be going wrong, or any additional steps I should take to debug this scenario? What's the best practice here? My development environment is Linux. Any help would be greatly appreciated! I'm working on a application that needs to handle this.
