IHttpContextAccessor in Azure Functions Isloated

Question

I currently checking what needs to be done to migrate a dotnet core In-process azure function v3 to a dotnet coe Out-of-process/.NET Isolated azure function.

In my project the IHttpContextAccessor is used to get the HttpContext in some places. I tried to get the IHttpContextAccessor in the function, but it is null.

Is it possible to get the IHttpContextAccessor in Azure Function Isolated or do I need to change the code to no longer use it?

            var host = new HostBuilder()
                .ConfigureFunctionsWorkerDefaults()
                .ConfigureServices(s =>
                {
                    s.AddHttpContextAccessor();
                })
                .Build();

        private readonly IHttpContextAccessor httpContextAccessor;

        public Function1(IHttpContextAccessor httpContextAccessor)
        {
            this.httpContextAccessor = httpContextAccessor;
        }

        [Function("Function1")]
        public HttpResponseData Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequestData req,
            FunctionContext executionContext)
        {
            var logger = executionContext.GetLogger("Function1");
            logger.LogInformation(httpContextAccessor.HttpContext.Request.Scheme);
