how to fetch __getLastResponse, __getLastResponseHeaders,....

[fglueck]

I got an error: "The request is invalid." To find the error I try

$this->api->getClient()->__getLastResponse(); $this->api->getClient()->__getLastRequest();

But all of this will trigger a Exception. Returns getClient() not a NTLMSoapClient (extends SoapClient)? $this->api was created with: API::withCallbackToken('outlook.office365.com', $token, $conf['options']);

Is there anyone that can help me in this misunderstood?
