"Unmarshalling Error: null" Response

[Ami Assayag]

I am constructing the SOAP xml and sending with a valid access token. The transaction looks similar to the samples found in the NoClientLibrary for dot net. but I am getting this bad response back:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>Unmarshalling Error: null </faultstring></soap:Fault></soap:Body></soap:Envelope>

 

Here is my body:

<?xml version="1.0" encoding="UTF-8"?>
<env:envelope
  xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <env:Header>
    <RequestHeader
      xmlns="https://www.google.com/apis/ads/publisher/v201403">
      <networkCode
        xmlns="https://www.google.com/apis/ads/publisher/v201403">MyNetworkCodeHere
      </networkCode>
      <applicationName
        xmlns="https://www.google.com/apis/ads/publisher/v201403">DFP Integration Test
      </applicationName>
      <authentication xsi:type="OAuth"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance>"
        xmlns="https://www.google.com/apis/ads/publisher/v201403">
        <parameters>My.Access.Token.Here</parameters>
      </authentication>
    </RequestHeader>
  </env:Header>
  <env:Body>
    <getCompaniesByStatement
      xmlns="https://www.google.com/apis/ads/publisher/v201403">
      <filterStatement>
        <query>WHERE name = 'XYZ' LIMIT 1</query>
      </filterStatement>
    </getCompaniesByStatement>
  </env:Body>
</env:envelope>

Is there a way to get more detailed description of what's wrong with the transaction?

Did anybody see this problem before? How did you fix it?

Thanks!

Finally got this right.. See the xml below.

If anybody from Google reads this... The documentation on how transactions should look like is missing, outdated, and in some places wrong. I understand that you want developers to use client libraries, but there are other developers (like me) that don't code in languages that have client library support, and need all the tiny details.

Here is how a good transaction should look like...

<?xml version="1.0" encoding="UTF-8"?>
<env:envelope
  xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"

  <env:Header>

    <ns1:RequestHeader         actor="http://schemas.xmlsoap.org/soap/actor/next"         mustUnderstand="0" xsi:type="ns1:SoapRequestHeader"
      xmlns:ns1="https://www.google.com/apis/ads/publisher/v201403"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <ns1:authentication xsi:type="ns1:OAuth"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">

      </ns1:authentication>
      <ns1:networkCode xsi:type="xsd:string"

        xmlns:xsd="http://www.w3.org/2001/XMLSchema">app.name      
      </ns1:applicationName>
    </ns1:RequestHeader>

  </env:Header>
  <env:Body>
    <getCompaniesByStatement
      xmlns="https://www.google.com/apis/ads/publisher/v201403">
      <filterStatement>

        <query>WHERE name = 'xyz' LIMIT 1</query>

Hi Ami,

I'll make sure the dot net example gets updated. For the record, what language are you using? 

Thanks,

I'm using apex. Unfortunately I can't use the wsdl because the conversion program does not work well (also, just eyeballing the wsdl, I it doesn't look like the authentication node has a parameters child, which i think is required). Now I'm writing XML to a string and sending as an http request and my hang up was strictly related to formatting.

The NoClientLibrary page has been updated on the github wiki:

https://github.com/googleads/googleads-dfp-dotnet-lib/wiki/NoClientLibrary

For anyone looking for more details on SOAP requests, there's also this guide in our documentation that has an example request/response:
