Adwords SOAP XML request against ManagedCustomerService fails - soap

Question

I'm working with https://adwords.google.com/api/adwords/mcm/v201402/ManagedCustomerService and wanting to get the account hierarchy.
The requests are being made in raw XML (controlled by JScript) -- a bit perverse, I know, but that's the situation.
I've generated the following SOAP packet
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Header>
<ns1:RequestHeader soapenv:actor="http://schemas.xmlsoap.org/soap/actor/next" soapenv:mustUnderstand="0" xmlns:ns1="https://adwords.google.com/api/adwords/mcm/v201402">
<ns1:clientCustomerId>some_ccid</ns1:clientCustomerId>
<ns1:developerToken>some_developer_token</ns1:developerToken>
<ns1:userAgent>GAS</ns1:userAgent>
<ns1:validateOnly>false</ns1:validateOnly>
<ns1:partialFailure>false</ns1:partialFailure>
</ns1:RequestHeader>
</soapenv:Header>
<soapenv:Body>
<get xmlns="https://adwords.google.com/api/adwords/mcm/v201402">
<serviceSelector>
<fields>Login</fields>
<fields>Customer</fields>
<fields>Name</fields>
<predicate>
<field>id</field>
<operator>GREATER_THAN</operator>
<values>0</values>
</predicate>
</serviceSelector>
</get>
</soapenv:Body>
</soapenv:Envelope>
Please note the idGREATER_THAN0. This is my naive way of getting everything.
I notice that the PHP GetAccountHierarchy.php has
// Create selector.
$selector = new Selector();
// Specify the fields to retrieve.
$selector->fields = array('Login', 'CustomerId', 'Name');
// Make the get request.
$graph = $managedCustomerService->get($selector);
This would seem to imply that no predicate has been defined. However, I'm a bit leery of doing that because the documentation says (yes, I do read the friendly manual), "predicates ContentsNotNull"
The response I get is
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<ns2:ResponseHeader xmlns:ns2="https://adwords.google.com/api/adwords/mcm/v201402" xmlns="https://adwords.google.com/api/adwords/cm/v201402">
<requestId>0004f553e08eaca00abc25900000893f</requestId>
<serviceName>ManagedCustomerService</serviceName>
<methodName>get</methodName>
<operations>0</operations>
<responseTime>141</responseTime>
</ns2:ResponseHeader>
</soap:Header>
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>[QuotaCheckError.INVALID_TOKEN_HEADER # ]</faultstring>
<detail>
<ns2:ApiExceptionFault xmlns="https://adwords.google.com/api/adwords/cm/v201402" xmlns:ns2="https://adwords.google.com/api/adwords/mcm/v201402">
<message>[QuotaCheckError.INVALID_TOKEN_HEADER # ]</message>
<ApplicationException.Type>ApiException</ApplicationException.Type>
<errors xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="QuotaCheckError">
<fieldPath/>
<trigger/>
<errorString>QuotaCheckError.INVALID_TOKEN_HEADER</errorString>
<ApiError.Type>QuotaCheckError</ApiError.Type>
<reason>INVALID_TOKEN_HEADER</reason>
</errors>
</ns2:ApiExceptionFault>
</detail>
</soap:Fault>
</soap:Body>
</soap:Envelope>
What am I doing incorrectly that I should get such a response?
BTW, if I do leave out the predicate or specify it with a null content, I still get the QuotaCheckError.INVALID_TOKEN_HEADER error.

A solution has been provided on the Adwords API google group. Working nicely now!
