原因

异常由格式错误的 appsettings.json 或 appsettings.Production.json 文件引起。

异常包括配置文件中需要更正的行，以及有问题的结构。在上面的示例中，为：

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

解决方案

1. 更正文件的语法。您可以使用 JSON 验证器（例如 JSON 在线验证器和格式化程序）来检查错误。

2. 在 IIS 中重新启动 Orchestrator。

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

原因

在 appsettings.Production.json 文件声明的存储中找不到证书，或者应用程序池无法访问证书的私钥。

重要提示：

从 Windows 证书查看器复制指纹时，请确保未插入不可见字符。

解决方案

1. 确保证书包含在 appsettings.Production.json 文件的证书存储中。

在此示例中，应用程序在 LocalMachine 位置查找具有 0A38CB4B920B2FE107051C32EBE7BA898CCE0441 指纹的证书。

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

有关详细信息，请参阅“私钥证书”页面。

2. 确保运行应用程序池的用户具有私钥的访问权限。

3. 在 IIS 中重新启动 Orchestrator。

此外，请查看“安装后更改证书”部分，了解详细信息。

原因

修改了 appsettings.Production.json 文件但未解密。

解决方案

1. 使用“加密 AppSettings.Production.json”页面“解密”部分中的命令解密 appsettings.Production.json文件。

2. 更新 appsettings.Production.json 文件。

3. 加密 appsettings.Production.json 文件。

原因

未在 appsettings.Production.json 或 Azure 应用程序服务设置中配置 SigningCredentialSettings 属性。

或

ASPNET_ENVIRONMENT 环境变量设置为 Production 以外的变量，这可防止从 appsettings.Production.json 读取设置。

解决方案

对于 Windows 服务器

确保 appsettings.Production.json 文件包含 SigningCredentialSettings 部分。示例：

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

对于 Azure 应用程序服务

确保正确配置了“发布到 Identity Server”页面第 5 步中列出的设置。

原因

更新服务器连接字符串的 MultiSubnetFailover 参数未设置为 true。

解决方案

1. 更正所有连接字符串，以将其 MultiSubnetFailover 参数设置为 true。

2. 在 IIS 中重新启动 Orchestrator。

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

异常

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

在受 CPU 使用率和内存消耗偏高影响的环境中，启动时间限制可能会受到限制，并导致停机。

解决方案

升级到 20.10.5 及更高版本，以将启动时间限制增加到 300 秒。

如果这还不够，则意味着服务器正在尝试执行某些操作，并且存在死锁。当 EnableMigrations 参数设置为 True 时，通常就会出现这种情况，并且有一个大型迁移挂起主线程。

如果该标志设置为 False，请收集内存转储，并将其提交给客户代表。
