Ursache

Die Ausnahme wird durch eine falsch formatierte appsettings.json- oder appsettings.Production.json-Datei verursacht.

Die Ausnahme enthält die Zeile der Konfigurationsdatei, die korrigiert werden muss, sowie die fehlerhaften Strukturen. Im obigen Beispiel ist dies:

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

Lösung

1. Korrigieren Sie die Syntax der Datei. Sie können eine JSON-Validierung wie JSON Online Validator and Formatter verwenden, um auf Fehler zu prüfen.

2. Starten Sie den Orchestrator in IIS neu.

Ursache

Das Zertifikat kann in dem Speicher, der in der appsettings.Production.json-Datei deklariert ist, nicht gefunden werden oder der Anwendungspool kann nicht auf den privaten Schlüssel des Zertifikats zugreifen.

Wichtig:

Stellen Sie sicher, dass Sie beim Kopieren des Fingerabdrucks aus der Windows-Zertifikatanzeige keine unsichtbaren Zeichen einfügen.

Lösung

1. Stellen Sie sicher, dass das Zertifikat im Zertifikatspeicher in der appsettings.Production.json-Datei enthalten ist.

In diesem Beispiel suchen die Anwendungen nach dem Zertifikat mit dem Fingerabdruck 0A38CB4B920B2FE107051C32EBE7BA898CCE0441 am Speicherort LocalMachine.

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

Weitere Informationen finden Sie auf der Seite Zertifikate mit privaten Schlüsseln.

2. Stellen Sie sicher, dass der Benutzer, unter dem der Anwendungspool ausgeführt wird, über Zugriffsrechte für den privaten Schlüssel verfügt.

3. Starten Sie den Orchestrator in IIS neu.

Und lesen Sie auch den Abschnitt Ändern von Zertifikaten nach der Installation für zusätzliche Informationen.

Ursache

Die appsettings.Production.json-Datei wurde ohne Entschlüsselung geändert.

Lösung

1. Entschlüsseln Sie die Datei appsettings.Production.json mit dem Befehl im Abschnitt Entschlüsselung auf der Seite Verschlüsseln von AppSettings.Production.json.

2. Aktualisieren Sie die Datei appsettings.Production.json.

3. Verschlüsselt die Datei appsettings.Production.json.

Ursache

Die Eigenschaft SigningCredentialSettings ist nicht in appsettings.Production.json oder in den Azure App Service-Einstellungen konfiguriert.

ODER

Eine ASPNET_ENVIRONMENT-Umgebungsvariable ist nicht auf Production festgelegt, was verhindert, dass die Einstellungen von appsettings.Production.json gelesen werden.

Lösung

Für Windows Server

Stellen Sie sicher, dass die Datei appsettings.Production.json den Abschnitt SigningCredentialSettings enthält. Beispiel:

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

Für Azure App Service

Stellen Sie sicher, dass die in Schritt 5 auf der Seite Veröffentlichen auf Identity Server beschriebenen Einstellungen korrekt konfiguriert sind.

Ursache

Für die Verbindungszeichenfolge „Server aktualisieren“ ist der Parameter MultiSubnetFailover nicht auf true festgelegt.

Lösung

1. Korrigieren Sie alle Verbindungszeichenfolgen, sodass ihr Parameter MultiSubnetFailover auf true festgelegt ist.

2. Starten Sie den Orchestrator in IIS neu.

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

Ausnahme

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.

Ursache

Das Startzeitlimit kann restriktiv sein und in Umgebungen mit hoher CPU-Auslastung und hohem Speicherverbrauch zu Ausfallzeiten führen.

Lösung

Upgraden Sie auf 20.10.5+, um das Startzeitlimit auf 300 Sekunden zu erhöhen.

Wenn das nicht ausreicht, bedeutet es, dass der Server versucht, etwas auszuführen, aber einen Deadlock hat. Dies ist für gewöhnlich der Fall, wenn der Parameter EnableMigrations auf True festgelegt ist und eine große Migration den Haupt-Thread zum Stillstand bringt.

Wenn das Flag auf False festgelegt ist, erstellen Sie einen Speicherauszug und senden Sie ihn an Ihren Kundenbetreuer.
