我正在尝试通过首先使用 ProvisionedApplicationPlatformSettings 创建和建立 CollaborationPlatform 来创建 ApplicationEndpoint，当我执行时：
ProvisionedApplicationPlatformSettings settings = new ProvisionedApplicationPlatformSettings("MYAPP", _appID);
_collabPlatform = new CollaborationPlatform(settings);
_collabPlatform.BeginStartup(EndPlatformStartup, _collabPlatform);
在EndPlatformStartup执行时的方法中collabPlatform.EndStartup(ar);我得到一个错误
ProvisioningFailureException:
One or more values in the configured settings are invalid or unusable. Check inner exception and logs for more details.
The settings wrapper failed to initialize.
