[JAVA] An invalid XML character (Unicode: 0x8) was found in the element content of the document

[Brandon]

Hi,

I was trying to download some specific ads from AdWords.

Everything goes fine except one ad returned a null SOAP response.

Is there something wrong with this ad?

The SOAP response: null

Any idea?

Hi,

That error means that somehow there's an embedded backspace (Unicode 0x8) in your ad. Did you create the ad via the API or from the UI?

One way you may be able to fix this is to edit the ad in the UI. However, when you do this it will actually remove the current ad and replace it with a new one, so stats after the change will appear under a new ad ID.

Thanks,

Josh, AdWords API Team

Hi Josh,

Thanks!

We create all ads from the UI.

I'm just wondering, could you trimmed it before user submit invalid context?

Hi Brandon,

I passed on the ad ID, etc. to the team that handles the UI to see if there was a validation step that we could add to prevent this from happening going forward. I'll post back if I hear back from them.

Thanks,
