Origine

L’exception est causée par un fichier appsettings.json ou appsettings.Production.json incorrect.

L’exception comprend la ligne du fichier de configuration qui doit être corrigée, ainsi que les structures incriminées. Dans l’exemple ci-dessus, il s’agit de :

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

Solution

1. Corriger la syntaxe du fichier. Vous pouvez utiliser un validateur JSON, tel que JSON Online Validator and Formatter, pour vérifier les erreurs.

2. Redémarrer Orchestrator dans IIS.

Origine

Le certificat est introuvable dans le magasin déclaré dans le fichier appsettings.Production.json, ou le pool d’applications ne peut pas accéder à la clé privée du certificat.

Important :

Assurez-vous de ne pas insérer de caractères invisibles lors de la copie de l’empreinte à partir de l’observateur de certificats Windows.

Solution

1. Assurez-vous que le certificat est inclus dans le magasin de certificats dans le fichier appsettings.Production.json.

Dans cet exemple, les applications recherchent le certificat avec l’empreinte numérique 0A38CB4B920B2FE107051C32EBE7BA898CCE0441 à l’emplacement LocalMachine.

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

Pour plus de détails, consultez la page Certificats de clé (Private key certificates).

2. Assurez-vous que l’utilisateur sous lequel le pool d’applications s’exécute dispose de droits d’accès pour la clé privée.

3. Redémarrer Orchestrator dans IIS.

En outre, consultez la section Modification des certificats après l’installation (Changing Certificates After Installation) pour plus de détails.

Origine

Le fichier appsettings.Production.json a été modifié sans déchiffrage.

Solution

1. Déchiffrez le fichier appsettings.Production.json à l’aide de la commande située dans la section Déchiffrage (Decryption) de la page Chiffrement du fichier AppSettings.Production.json (Encrypting AppSettings.Production.json).

2. Mettez à jour le fichier appsettings.Production.json.

3. Chiffrez le fichier appsettings.Production.json.

Origine

La propriété SigningCredentialSettings n’est pas configurée dans appsettings.Production.json ou dans les paramètres d’Azure App Service.

OU

Une variable d’environnement ASPNET_ENVIRONMENT est définie sur quelque chose d’autre que Production, ce qui empêche les paramètres d’être lus à partir de appsettings.Production.json.

Solution

Pour Windows Server

Assurez-vous que le fichier appsettings.Production.json contient la section SigningCredentialSettings. Exemple :

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

Pour Azure App Service

Assurez-vous que les paramètres décrits à l’étape 5 de la page Publier sur Identity Server (Publish to Identity Server) sont configurés correctement.

Origine

La chaîne de connexion de mise à jour du serveur n’a pas le paramètre MultiSubnetFailover défini sur true.

Solution

1. Corrigez toutes les chaînes de connexion de sorte que leur paramètre MultiSubnetFailover est défini sur true.

2. Redémarrer Orchestrator dans IIS.

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.

Origine

La limite de temps de démarrage peut être restrictive et entraîner des temps d’arrêt dans les environnements affectés par une utilisation élevée du processeur et une forte consommation de mémoire.

Solution

Passez àla version 20.10.5+ pour augmenter la limite de temps de démarrage à 300 secondes.

Si cela est insuffisant, cela signifie que le serveur tente d’exécuter quelque chose et a rencontré un blocage. Cela est souvent le cas lorsque le paramètre EnableMigrations est défini sur True et qu’il y a une grande migration suspendue au thread principal.

Si l’indicateur est défini sur False, collectez une copie de la mémoire et soumettez-la à votre représentant client.
