SOAP-ERROR: Encoding: Error calling from_xml callback

[Mustafa D.]

Hi,
201109 I want to use the new version.
However, I receive an error like the following example php files in
general. What is the source of this problem. Please help.

SOAP-ERROR: Encoding: Error calling callback from_xml

Thank you for your help.

Hi,

  Are you using the PHP client library? Do you receive a SOAP XML response or is this breaking in the request phase?  Any additional information you can provide about exactly what is happening when this error occurs will help us troubleshoot.

I'm having the same problem.

Line: 202, file: aw_api_php_lib_2.7.1/src/Google/Api/Ads/Common/Lib/
AdsSoapClient.php
Exception: SOAP-ERROR: Encoding: Error calling callback from_xml
Backtrace:

The server is debian with PHP5.2
The same script is working without problem on Win7 + PHP5.3

Hi,

I'm not able to emulate this with PHP 5.2.4.  Can you provide more details about the environment you are running this on?

Best,

Hi Francesco,

I'm having trouble installing 5.2.0 on my system, so I'm not able to test this directly.  I think what's going on is that the from_xml callback (AdsSoapClient::TypemapLongFromXml) is running into an error when trying to parse the XML (in XmlUtils::GetDomFromXml).  Can you try catching the exception there and see what the underlying cause is?  Perhaps also take a look at the XML it's trying to parse.

Best,

- Eric
