function input Binding with cosmosDb not working

[badrdouah]

Hi,

I've been trying to bind a cosmosdb input with an azure function with no luck, i'm developing the function locally using .net , when i deploy it it shows the following schema in the integration blade

here is my .net function

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;

//         
namespace cosmosDBFunc
{
    public static class cosmosDBFunc
    {
        [FunctionName("cosmosDBFunc")]
        public static IActionResult Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequest req,

        [CosmosDB("MY DB NAME", "MY CONTAINER NAME", Connection = "MY CONNECTION STR ENV VARIABLE NAME")] dynamic myContent, ILogger log)
        {

            var json = JsonConvert.SerializeObject(myContent);
            return new OkObjectResult(json);
        } 
    }
}

My function.json
