I am getting repeated CONCURRENT_MODIFICATION errors trying to create a Responsive Text Ad. I checked for the usual causes of this exception according to the documentation and other discussions in this forum, and none of them apply. I can reproduce it trying to create a single ad through the API with nothing else modifying AdWords. Is this a known bug on the server? Thanks.

The AdWords UI also has a bug in it where it drops one of the headlines. My guess is that there is an off-by-one error in the Ads backend which is manifesting as a CONCURRENT_MODIFICATION at the API level and a dropped headline in the Ads UI interface. I figured out how to workaround the off-by-one error in the UI by adding one more headline than I actually want. Beta feature right? :-)

Hi Jon,

The DatabaseError.CONCURRENT_MODIFICATION error that you encountered could occur due to multiple processes that are trying to update the same entity at the same time. It includes a user in the AdWords web interface that is updating the entity while you are updating as well via the API. However, to further investigate your issue, could you please send to me (via reply privately to author) the complete SOAP request and response logs of the operation which returns this error?

Thanks and regards,

Luis

The bug appears to be fixed now. Is it fixed for you Scott?

Hi Jon,

Thank you for the confirmation.

Hi Scott,

Could you confirm if you still encountered the error? If so, could you provide the complete SOAP request and response logs so I could further investigate the issue? Please reply via Reply privately to author.
