Invalid XML character error

[Ilya Borisenko]

Hi!

We are observing the following error while performing a request to AdGroupAdService via the SDK:

An invalid XML character (Unicode: 0xb) was found in the element content of the document.

Looks like the service is returning a symbol that causes the XML deserializer to fail. Here's the SDK-related part of the stack trace. Is there a way to handle this on our side without making changes to the data?

Caused by: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 4743; An invalid XML character (Unicode: 0xb) was found in the element content of the document.

Hi,

Thank you for reaching out to our API support team.

Since it appears that the issue is related to the Java client library, I would recommend that you reach out to the Java client library owners instead, via this link, for further insight and guidance.
