Hi,
Today we found strange behavior with PQL statement requests for one of our clients, networkCode=95377733.
DFP library version is v201502.
Request example:
Creative[] creatives = creativeServiceInterface.getCreativesByStatement(filterStatement).getResults();
translates to SOAP request:
<?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 xmlns:ns1="https://www.google.com/apis/ads/publisher/v201502" soapenv:mustUnderstand="0">
<ns1:networkCode>95377733</ns1:networkCode>
<ns1:applicationName>AdMax (DfpApi-Java, Dfp-Axis/1.39.0, Common-Java/1.14.1, Axis/1.4, Java/1.8.0_51, maven)</ns1:applicationName>
</ns1:RequestHeader>
</soapenv:Header>
<soapenv:Body>
<getCreativesByStatement xmlns="https://www.google.com/apis/ads/publisher/v201502">
<filterStatement>
<query>WHERE lastModifiedDateTime >= '2015-10-22T04:06:23'</query>
</filterStatement>
</getCreativesByStatement>
</soapenv:Body>
</soapenv:Envelope>Take a look on query.
<query>WHERE lastModifiedDateTime >= '2015-10-22T04:06:23'</query>
It should be "greater or equal" condition (>=), but here is ">=".
SOAP response in such case:
<?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">

Hi Tatiana,
This isn't a problem with the > characters. That's just the XML escaped equivalent of >.
Is the error you provided from that exact request? These are typically caused by a problematic entity in the DFP network. If you can provide an exact SOAP request that causes the error it'll help me track it down.
Thanks,
Chris Seeley, DFP API Team

Hi, Chris,
Yes, of course, error I provided is from provided request. Unfortunately, I can't define concrete entity to help you.

Hi,
I found some details.
Problem creative entity can be found with following request:
<?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">

<ns1:RequestHeader xmlns:ns1="https://www.google.com/apis/ads/publisher/v201502" soapenv:mustUnderstand="0">
<ns1:networkCode>95377733</ns1:networkCode>
<ns1:applicationName>AdMax (DfpApi-Java, Dfp-Axis/2.5.0, Common-Java/1.14.1, Axis/1.4, Java/1.8.0_51, maven)</ns1:applicationName>
</ns1:RequestHeader>
</soapenv:Header>
<soapenv:Body>
<getCreativesByStatement xmlns="https://www.google.com/apis/ads/publisher/v201502">
<filterStatement>
<query>WHERE lastModifiedDateTime >= '2015-10-22T04:06:23' LIMIT 1 OFFSET 282</query>
</filterStatement>
</getCreativesByStatement>
</soapenv:Body>
</soapenv:Envelope>Checking one by one I found offset number 282, which fails. But I can't get any details (ID is mostly interested) via API - CreativeServiceInterface#getCreativesByStatement try return CreativePage entirely and return error. Can you find on your side ID of this problem entity?

Hi Tatiana,
Thanks for the extra information. I found a custom creative with invalid characters that's causing this. Its ID is 84640729693. You can skip this ID in your filter for now, and work with the client to correct the creative via the UI. The invalid characters are contained in the HTML snippet.
Thanks,
