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

Causa

A exceção é causada por um arquivo appsettings.json ou appsettings.Production.json malformado.

A exceção inclui a linha do arquivo de configuração que precisa ser corrigido, junto com as estruturas ofensivas. No exemplo acima, isto é:

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

Solução

1. Corrija a sintaxe do arquivo. Você pode usar um validador JSON, como o Validador Online JSON e o Formatter, para verificar erros.

2. Reinicie o Orchestrator no IIS.

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

Causa

O certificado não pode ser encontrado no armazenamento declarado no arquivo appsettings.Production.json ou o pool de aplicativos não pode acessar a chave privada do certificado.

Importante:

Certifique-se de não inserir caracteres invisíveis ao copiar a impressão digital do visualizador de certificados do Windows.

Solução

1. Certifique-se de que o certificado esteja incluído no armazenamento de certificados dentro do arquivo appsettings.Production.json.

Neste exemplo, os aplicativos pesquisam o certificado com a impressão digital 0A38CB4B920B2FE107051C32EBE7BA898CCE0441 no local LocalMachine.

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

Para obter detalhes, consulte a página Certificados de chave privada.

2. Certifique-se de que o usuário sob o qual o pool de aplicativos está sendo executado tenha direitos de acesso para a chave privada.

3. Reinicie o Orchestrator no IIS.

Além disso, consulte a seção Alteração de certificados após a instalação para obter detalhes.

Causa

O arquivo appsettings.Production.json foi modificado sem descriptografia.

Solução

1. Descriptografe o arquivo appsettings.Production.json usando o comando na seção Descriptografia da página Criptografia do AppSettings.Production.json.

2. Atualize o arquivo appsettings.Production.json.

3. Criptografe o arquivo appsettings.Production.json.

Causa

A propriedade SigningCredentialSettings não está configurada em appsettings.Production.json ou nas configurações do Azure App Service.

OU

Uma variável de ambiente ASPNET_ENVIRONMENT é definida como algo diferente de Production, o que impede que as configurações sejam lidas a partir de appsettings.Production.json.

Solução

Para o Windows Server

Certifique-se de que o arquivo appsettings.Production.json contenha a seção SigningCredentialSettings. Exemplo:

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

Para o Azure App Service

Certifique-se de que as configurações descritas na etapa 5 da página Publicar no Identity Server estejam configuradas corretamente.

Causa

A string de conexão Atualizar servidor não tem o parâmetro MultiSubnetFailover definido como true.

Solução

1. Corrija todas as strings de conexão de modo que seu parâmetro MultiSubnetFailover esteja definido como true.

2. Reinicie o Orchestrator no IIS.

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

Exceção

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.

Causa

O limite de tempo de inicialização pode ser restritivo e causar tempo de inatividade em ambientes afetados pelo alto uso de CPU e consumo de memória.

Solução

Atualize para a versão 20.10.5 ou superior para aumentar o limite de tempo de inicialização para 300 segundos.

Se isso for insuficiente, significa que o servidor está tentando executar algo e tem um impasse. Este é geralmente o caso quando o parâmetro EnableMigrations é definido como True, e há uma grande migração suspensa no thread principal.

Se o sinalizador estiver definido como False, colete um despejo de memória e envie-o para o representante do cliente.
