Isolated Azure Function missing authentication header?

I have created a new .NET 6 Isolated Azure Function followed by this great article: https://joonasw.net/view/azure-ad-jwt-authentication-in-net-isolated-process-azure-functions

If I'm debugging it locally, it works perfectly, the calling client attaches an authentication header to the request which I can read in the authentication middleware. But once the function app is deployed in Azure, I cannot access the authentication header in the authentication middleware, this header entry is missing. It looks like the authentication header is somehow removed from the header.

My program is

public static void Main()
    {
        var host = new HostBuilder()
            .ConfigureFunctionsWorkerDefaults(builder =>
            {
                builder.UseNewtonsoftJson();
                builder.UseMiddleware<AuthenticationMiddleware>();
                builder.UseMiddleware<AuthorizationMiddleware>();
                builder.UseMiddleware<ExceptionHandlerMiddleware>();
                builder.Services.AddOptions<AppSettings>()
                             .Configure<IConfiguration>((settings, configuration) =>
                             {
                                 configuration.GetSection("AppSettings").Bind(settings);
                             });
                builder.Services.AddPersistenceRepositories();
                builder.Services.AddPersistenceServices();
                builder.Services.AddPersistenceInfrastructures();
                builder.Services.AddSingleton<IHttpFunctionExecutor, HttpFunctionExecutor>();
            })
            .ConfigureOpenApi()
            .Build();

        host.Run();
    }

Thank you @jack.pop ,For the solution ,Posting the same as answer so that other community members can beneficial for similar issue.

WORKAROUND:-

Please make sure to set the authorization level to Anonymous as shown below .

public static class TestFunctions
{
    [Authorize(
        Scopes = new[] { "access_as_user" },
        UserRoles = new[] { "admin" })]
    public static HttpResponseData OnlyAdmins(
        [HttpTrigger(AuthorizationLevel.Anonymous, "get")] HttpRequestData req,
        FunctionContext executionContext)
    {
    }
}
