Handle an exception

Alibaba Cloud SDK V1.0 for PHP raises two exception types: ServerException for server-side errors and ClientException for client-side errors. If the server does not receive the request, no request ID is available. If the server receives the request, you can obtain the request ID from the exception and provide it to Alibaba Cloud technical support for troubleshooting.
