Azure function with HttpTrigger is not getting executed

Question

Hello folks, after migrating my code to latest Azure Function with .NET 7 (isolated process), I am having an issue trying to call all of my azure functions with an http trigger. In the azure function console, I can see I am calling the right endpoint, as you can see from the picture below:

Here is how the function is implemented:

[Function("uploading-process")]
 public async Task Run(
     [HttpTrigger(AuthorizationLevel.Anonymous, "post")]
     HttpRequest request,
     FunctionContext executionContext,
     CancellationToken cancellationToken,
     ILogger logger)
{
   		try
            {
                var globalConfig = GlobalConfig.Create(() =>
                    new AutofacConfig()
                        .ConfigTelemetryExecutionContextProvider(executionContext)
                        .ConfigDocumentClient(_cosmosClient)
                        .DefaultConfig()
                        .BuildContainer());
                await globalConfig.Container.ResolveNamed<IActivityMediator>("update-internalstatus-mediator")
                    .ExecuteAsync(batch, cancellationToken);

            } 
            catch(Exception ex)
            {
                _telemetryClient.TrackException(ex);
            }
        }
}

This is my host.json file:

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[3.3.0, 4.0.0]"
  },
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  }
}

Hope the info I provided are enough. Do you have any idea why this is happening?

I fixed the issue just creating a new Azure Function and updating the code as follows:

Program.cs changed a bit the structure:

using Microsoft.AspNetCore.Server.Kestrel.Core;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
    .ConfigureServices(services =>
    {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();
        services.Configure<KestrelServerOptions>(options =>
        {
            options.AllowSynchronousIO = true;
        });
    })
    .Build();

host.Run();

host.json removed useless code:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      },
      "enableLiveMetricsFilters": true
    }
  }
}

.csproj changed few versions:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <OutputType>Exe</OutputType>

Function with endpoint, small changes in the structure:

using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using Autofac;
using Microsoft.Azure.Cosmos;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Azure.Functions.Worker.Http;
using Microsoft.DurableTask.Client;
using Microsoft.Extensions.Logging;
using Microsoft.AspNetCore.Http;
using Microsoft.WindowsAzure.Storage.Queue;
using Microsoft.WindowsAzure.Storage;
using RevisoAgyoModels;
using RevisoAgyoServices;
using RevisoAgyoWorkflow.DownloadDocumentsByDates.Implementations;
namespace RevisoAgyoWorkflow.DownloadDocumentsByDates.EntryPoints
{
    public class DownloadDocumentsByDates
    {
        [Function("DownloadDocumentsByDates_HttpStart")]
        public static async Task<HttpResponseData> HttpStart(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req, 
            [DurableClient] DurableTaskClient starter,
            FunctionContext _executionContext)
        {
            ILogger _logger = _executionContext.GetLogger(nameof(DownloadDocumentsByDates));
            var cosmosDbConnectionString = Environment.GetEnvironmentVariable("CosmosDb_connectionString"); 
            var downloadDocumentQueueConnectionString = Environment.GetEnvironmentVariable("DownloadDocument_connectionString"); 
            var downloadDocumentQueueName = Environment.GetEnvironmentVariable("DownloadDocument_queueName");
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(downloadDocumentQueueConnectionString);
            CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();
            CloudQueue queue = queueClient.GetQueueReference(downloadDocumentQueueName);
            var globalConfig = GlobalConfig.Instance(() =>
                    new AutofacConfig()
                        .DefaultConfig()
                        .ConfigCosmosClient(new CosmosClient(cosmosDbConnectionString))
                        .ConfigDownloadDocumentQueueStorage(queue)
                        .ConfigTelemetryExecutionContextProvider(_executionContext)
                        .BuildContainer());
            var _telemetry = globalConfig.Container.Resolve<ITelemetry>();
            var input = req.ReadFromJsonAsync<DownloadDocumentsByDatesParams>().Result;
            var executionContext = new TelemetryExecutionContext(_executionContext);
            string instanceId = null;
            IPurchaseInvoicesDownloadingService _purchaseInvoicesDownloadingService = null;
            ...
        }
    }
}

I do not know what exactly fixed the issue, but I made these changes based on what I had the new Azure Function and it worked.
