node-soap: It not found the distribution method
<p>Try using the node soap call a web service does not work, but if it works in SoapUI</p>

<pre><code>var soap = require('soap');
var url = 'http://190.129.208.178:96/PasarelaServices/CustomerServices?wsdl';
var args = { "key": '12345', "parametros": 'parameters...' };
soap.createClient(url, function (err, client) {
  console.log(client.describe());
  console.log(client.describe().CustomerServices.CustomerServicesPort.solicitarPago);
  client.CustomerServices.CustomerServicesPort.solicitarPago(args, function (err, result, raw, soapHeader) {
    console.log(err);
    console.log(result)
    console.log(raw);
  });
});
</code></pre>

<p>in SoapUI request would:</p>

<pre><code>&lt;soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.vlink.com.bo/"&gt;
   &lt;soapenv:Header/&gt;
   &lt;soapenv:Body&gt;
      &lt;ser:solicitarPago&gt;
         &lt;key&gt;12345&lt;/key&gt;
         &lt;parametros&gt;parameters...&lt;/parametros&gt;
      &lt;/ser:solicitarPago&gt;
   &lt;/soapenv:Body&gt;
&lt;/soapenv:Envelope&gt;
</code></pre>

<p>Thank you</p>
