I am getting an error when attempting to start my Azure Function App (.NET 8/Isolated worked model) locally (VS 2022)

I'm unable to get my Azure Function App to work in .NET 8.

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using <namespace>.FunctionApps.Extensions;
using Serilog;

var environment = Environment.GetEnvironmentVariable("AZURE_FUNCTIONS_ENVIRONMENT");

IConfiguration configuration = new ConfigurationBuilder()
    .AddJsonFile("host.json", optional: true, reloadOnChange: true)
    .AddJsonFile($"host.{environment}.json", optional: true, reloadOnChange: true)
    .AddEnvironmentVariables()
    .Build();

var logger = new LoggerConfiguration()
    .WriteTo.Console()
    .CreateLogger();

Log.Logger = logger;

var builder = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults()
    .ConfigureServices(services =>
    {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();

        services.RegisterServices(configuration, logger);

    });

var host = builder.Build();

host.Run();

I get the following Exception message when I hit the host.Run(); line

System.InvalidOperationException: 'The gRPC channel URI 'http://:' could not be parsed.'

The function I am trying to run is a Service Bus FA subscribing to Azure SB Queue

using Microsoft.Azure.Functions.Worker;
using <namespace>.Common.Helpers;
using <namespace>.InterimSolutionModels.Extensions;
using <namespace>.Models.DispatchMessages;
using <namespace>.ServiceBus;
using Serilog;

namespace <namespace>.FunctionApps.Functions.DistributionList
{
    public class DeleteDistributionList(ILogger logger)
    {
        private readonly ILogger _logger = logger;

        [Function(nameof(DeleteDistributionList))]
        [ServiceBusOutput(QueueNames.InterimProcessing, Connection = "ServiceBusConnectionString")]
        //public void Run([ServiceBusTrigger(QueueNames.Group.DistibutionListQueue.DeleteDistibutionList, Connection = "ServiceBusConnectionString")] ServiceBusReceivedMessage message)
        public string Run([ServiceBusTrigger(QueueNames.Group.DistibutionListQueue.DeleteDistibutionList, Connection = "ServiceBusConnectionString")] DistributionListDeleteMessage message)
        {
            _logger.Information($"Received Message: {message}");

            var interimDistibutionListDelete = message.ToInterimModel();

            var outPutJson = JsonHelper.ToJson(interimDistibutionListDelete);

            return outPutJson;
        }
    }
}

I updated the project templates and recreated the FA project in case that was an issue. I'm not sure if I missed a step somewhere (Azurite setup for example), if I am facing an issue from one of the libraries (I have found other places with the same parsing http exception but no solution) or I plain don't understand how this works yet...

What's getting me is that I am not using gRPC, so this has to be related to hosting / possibly my startup code.

Solution

  • I am getting an error when attempting to start my Azure Function App (.NET 8/Isolated worked model) locally (VS 2022.The function I am trying to run is a Service Bus FA subscribing to Azure SB Queue

    Below is how I use Serilog and Azure Service Bus Function App:

    Program.cs:

    using Microsoft.Extensions.Hosting;
using Serilog;

var host = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults()
    .ConfigureServices(services =>
    {

        Log.Logger = new LoggerConfiguration()
            .CreateLogger();
    })
    .Build();

host.Run();

    Function.cs:

    using System;
using Azure.Messaging.ServiceBus;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;

namespace FunctionApp113
{
    public class Function1
    {
        private readonly ILogger<Function1> _logger;

        public Function1(ILogger<Function1> logger)
        {
            _logger = logger;
        }

        [Function(nameof(Function1))]
        public void Run([ServiceBusTrigger("rithwik", Connection = "rithcon")] ServiceBusReceivedMessage message)
        {
            _logger.LogInformation("Message ID: {id}", message.MessageId);
            _logger.LogInformation("Message Body: {body}", message.Body);
            _logger.LogWarning("Message Content-Type: {contentType}", message.ContentType);
            _logger.LogCritical("Hello Rithwik");
        }
    }
}

    host.json:

    {
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    },
    "logLevel": {
      "FunctionApp113.Function1": "Information"
    }
  }
}

    local.settings.json:

    {
    "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",
    "rithcon": "Endpoint=sb://hiservice.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=chP9VP9/i7+ASbBs1ErI=",
    "APPLICATIONINSIGHTS_CONNECTION_STRING": "InstrumentationKey=42f478bf99;IngestionEndpoint=https://centralindia-0.in.applicationinsights.azure.com/;LiveEndpoint=https://centralindia.livediagnostics.monitor.azure.com/"

  }
}

    csproj:

    <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>

    </None>
  </ItemGroup>
  <ItemGroup>
    <Using Include="System.Threading.ExecutionContext" Alias="ExecutionContext" />
  </ItemGroup>
</Project>

    Output:

    After message is send to service bus queue then it is getting triggered like below:
