Estou desenvolvendo um gatilho http usando as funções azure 2.xe core dotnet, após a atualização mais recente do VS 2017 15.8.2. Estou recebendo o seguinte erro ao executar a função localmente

Estou executando as ferramentas do Function Core 2.0.1-Beta.35 e a versão de tempo de execução 2.0.11960.0

A função tem a seguinte aparência

using System.IO;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;

using Microsoft.Azure.WebJobs.Host;

using System;

namespace NWMposTransInput
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static IActionResult Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]
        HttpRequest req, ILogger log,
            [CosmosDB(
            databaseName: "xxxx",
            collectionName: "yyyy",
            ConnectionStringSetting = "CosmosDbConnection")]out dynamic document,
            ILogger log2)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");

            string name = req.Query["name"];

            string requestBody = new StreamReader(req.Body).ReadToEnd();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.name;

            document = new { SSourceSystem = "jongelSystem",
                             id = Guid.NewGuid(),
                             SSourceSystemVersion = "1.1",
                             STransactionId = "12345"};

            log.LogInformation($"C# Queue trigger function inserted one row");
            log.LogInformation($"Description={req.Body}");

            return name != null
                ? (ActionResult)new OkObjectResult($"Hello, {name}")
                : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
        }
    }

    public class NWCloudOrder
    {
        public string Id { get; set; }
        public string SSourceSystem { get; set; }
        public string SSourceSystemVersion { get; set; }
        public string STransactionId { get; set; }
    }
}

--- EDIT --- Certificando-se de usar o tempo de execução correto, isso agora produz o seguinte erro
