Application Insights ログ記録を実装しようとしています。
これが私のスタートアップです
configureservicesの下
services.AddApplicationInsightsTelemetry(Configuration["ApplicationInsights:InstrumentationKey"]);
これが私のコントローラーです
private readonly My_DevContext _context;
private Task t;
private readonly IKipReport _kipReport;
private readonly ILogger _logger;
public ReportExtractionController(ILogger logger,My_DevContext context, IKipReport kipReport)
{
_context = context;
_kipReport = kipReport;
_logger = logger;
}
// GET: api/<RepprtExtractionController>
[HttpGet]
public async Task<IActionResult> Get()
{
_logger.LogError("Trial");
}
APIを呼び出そうとすると、500内部サーバーエラー

私は.NET 5.0で作業しています
何を間違えたのか分かりません。

コードを以下のように変更します。
private readonly ILogger _logger;
public ReportExtractionController(ILogger<ReportExtractionController> logger)
{
_logger = logger;
}
