Identity Server の例外

500.30 ASP.NET Core app failed to start - System.FormatException: Could not parse the JSON file

Exception

Exception Info: System.FormatException: Could not parse the JSON file.

原因

この例外は、不正な形式の appsettings.json または appsettings.Production.json ファイルが原因で発生します。

例外には、修正が必要な構成ファイルの行と、問題のある構造が含まれます。上記の例では、次の行です。

System.Text.Json.JsonReaderException: '2' is an invalid start of a property name. Expected a '"'. LineNumber: 0 | BytePositionInLine: 1.

解決策

1. ファイルの構文を修正します。JSON オンライン バリデーターやフォーマッターなどの JSON バリデーターを使用してエラーをチェックできます。

2. IIS で Orchestrator を再起動します。

   at UiPath.IdentityServer.Web.Program.<Main>(String[] args)

原因

appsettings.Production.json ファイルで宣言されているストアに証明書が見つからないか、アプリケーション プールが証明書の秘密キーにアクセスできません。

重要:

Windows 証明書ビューアーから拇印をコピーするときに、非表示の文字を挿入しないように注意してください。

解決策

1. appsettings.Production.json ファイル内の証明書ストアに証明書が含まれていることを確認します。

この例では、アプリケーションは LocalMachine の場所で 0A38CB4B920B2FE107051C32EBE7BA898CCE0441 の拇印を持つ証明書を検索します。

"SigningCredentialSettings": {
      "StoreLocation": {
        "Name": "0A38CB4B920B2FE107051C32EBE7BA898CCE0441",
        "Location": "LocalMachine",
        "NameType": "Thumbprint"
      }

詳細については、「秘密キーの証明書」のページをご覧ください。

2. アプリケーション プールを実行しているユーザーが秘密キーへのアクセス権を持っていることを確認します。

3. IIS で Orchestrator を再起動します。

また、詳細については、「インストール後に証明書を変更する」をご覧ください。

   at UiPath.IdentityServer.Web.Program.<Main>(String[] args)

原因

appsettings.Production.json ファイルは復号されずに変更されました。

解決策

1. 「AppSettings.Production.json を暗号化する」ページの「復号」セクションのコマンドを使用して、appsettings.Production.json ファイルを復号します。

2. appsettings.Production.json ファイルを更新します。

3. appsettings.Production.json ファイルを暗号化します。

原因

SigningCredentialSettings プロパティは、 appsettings.Production.json や Azure App Service の設定では設定されません。

OR

ASPNET_ENVIRONMENT 環境変数が Production 以外に設定されているため、appsettings.Production.json から設定の読み取りができません。

解決策

Windows Server の場合

appsettings.Production.json ファイルに SigningCredentialSettings セクションが含まれていることを確認します。例：

"AppSettings": {
    [...]
    "SigningCredentialSettings": {
      "StoreLocation": {
        "Name": "0A38CB4B920B2FE107051C32EBE7BA898CCE0446",
        "Location": "LocalMachine",
        "NameType": "Thumbprint"
      }
    }

Azure App Service の場合

「Identity Server にパブリッシュする」ページの手順 5 で説明されている設定が正しく構成されていることを確認します。

原因

更新サーバーの接続文字列の MultiSubnetFailover パラメーターが true に設定されていません。

解決策

1. すべての接続文字列を修正して、MultiSubnetFailover パラメーターが true に設定されるようにします。

2. IIS で Orchestrator を再起動します。

500.30 ASP.NET Core app failed to start - Managed server didn't initialize after X ms

Exception

Application '/LM/W3SVC/1/ROOT' with physical root 'C:\Program Files (x86)\UiPath\APPLICATIONNAME\' failed to load coreclr. Exception message:
Managed server didn't initialize after X ms.

原因

起動制限時間は、CPU 使用率の高さやメモリ消費量の多さに影響を受ける環境で制限がかかり、ダウンタイムが発生することがあります。

解決策

20.10.5+ にアップグレードして、起動制限時間を 300 秒に増やします。

これでも不十分な場合は、サーバーが何かを実行しようとしていて、デッドロックが発生していることを意味します。これは通常、EnableMigrations パラメーターが True に設定され、メインスレッドをハングさせる大規模な移行がある場合に発生しています。

フラグが False に設定されている場合は、メモリ ダンプを収集し、顧客の担当者に送信します。
