'Cannot read property methodName of undefined' consuming a NodeJS SOAP method with document style

I have a NodeJS (node-soap) SOAP web service and it works good with rpc style when I consume it by POSTMAN, but I need to make it works with document style. When I change the style I have an exception with no much information. Next details:

WSDL (It works with style rpc):

<?xml version="1.0" encoding="UTF-8"?>

    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

Response is something like that:

<?xml version="1.0" encoding="utf-8"?>

                </tns:File>
            </tns:GetFilesResult>
        </tns:GetFilesResponse>
    </soap:Body>
</soap:Envelope>

POSTMAN request:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http:localhost:4205/files_service">

      <tns:Password>mypassword</tns:Password>
    </tns:GetFiles>
  </soap:Body>
</soap:Envelope>

Error when I change the style for document in the WSDL <s:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:tns="http://localhost:4205/files_service">
    <soap:Body>
        <soap:Fault>
            <soap:Code>
                <soap:Value>SOAP-ENV:Server</soap:Value>
                <soap:Subcode>
                    <soap:value>InternalServerError</soap:value>
                </soap:Subcode>
            </soap:Code>
            <soap:Reason>
                <soap:Text>TypeError: Cannot read property &apos;methodName&apos; of undefined</soap:Text>
            </soap:Reason>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

I don't have any idea why this fails with document style. Other thing is if I consume the method from a node-soap client I don't have the exception, I get the data correctly.

Answering my question, in the request I don't need to define the method, I need to define the request. I use SoapUI to get the correct request.

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http:localhost:4205/files_service">
  <soap:Body>
    <tns:GetFilesRequest>
      <tns:User>myuser</tns:User>
      <tns:Password>mypass</tns:Password>
    </tns:GetFilesRequest>
  </soap:Body>
</soap:Envelope>
