.NET 8 Azure Function App Получение ilogger = null ⇐ C#

[Anonymous]

Я выдвигаю свое первое приложение для функций .NET 8 в Azure, и я получаю ошибку, что ilogger является нулевой. Я следую тот же код, который я использовал ранее на .net 6. Он также работает так же, как и ожидалось, когда я запускаю приложение локально на моем машине разработки.

Код: Выделить всё

public class StorageUtilityHandler
{
private readonly ILogger _logger;
private readonly IBusinessLogic _businessLogic;

public StorageUtilityHandler(ILogger logger, IBusinessLogic businessLogic)
{
_logger = logger;
_businessLogic = businessLogic;
}

[Function("LogProcessorQueue")]
public static Task ProcessLogQueueAsync(
[ServiceBusTrigger("%LogServiceBusQueue%", Connection = "ServiceBusConnection")] string logFileMessage, ILogger log)
{
if (logFileMessage != null)
{
try
{
LogEntity? logEntity = JsonSerializer.Deserialize(logFileMessage);

if (logEntity != null)
{
// If ERROR then send out Email
if (logEntity.Message.Contains("ERROR"))
{
var _email = new EmailService();
_email.SendLogError(logEntity);
}

var storageConnection = Environment.GetEnvironmentVariable("StorageConnection");
var loggingTableName = Environment.GetEnvironmentVariable("LoggingTableName");

TableClient tableClient = new(storageConnection, loggingTableName);

// Create the table if it doesn't already exist to verify we've successfully authenticated.
tableClient.CreateIfNotExists();        //Remove in PROD

tableClient.AddEntity(logEntity);
}
}
catch (Exception ex)
{
log.LogError($"Error processing Log message. {ex.Message} | {ex.StackTrace} | {ex.InnerException}");
}
}

return Task.CompletedTask;
}
}

Program.cs

:
var host = new HostBuilder()
.ConfigureFunctionsWebApplication()
.ConfigureServices(services =>
{
services.AddApplicationInsightsTelemetryWorkerService();
services.ConfigureFunctionsApplicationInsights();

services.AddTransient();
})
.Build();
< /code>
All my Service Bus messages from this FA are going into the Dead Letter queue. Looking at the messages in the Dead Letter queue, they look correct. When I look at the logs from Application Insights, I get the following error about ILogger< /code> null. < /p>

operation_name: logprocessorQueue < /p>
