What is the issue?

When uploading new creatives to the platform, you may encounter a variation of the following error messages within the Activity Log:

Additionally, the creatives that display this error will be rejected and will not be posted to the publisher successfully.

What causes the issue?

This error message means that some part of the affected creative is too long. There are maximum character limits for headlines and description lines.

• This error message is from Google
• line_overflow means your description is too long
• What comes after operand.ad (in this case description2) tells you where the offending part of the creative is
• en_GB is the current language targeting setting

There are some countries you can target which will allow more than the allotted character limits, but if you are not targeting these, the creative will be rejected with the line_overflow error above.

How to fix the issue

The only solution to this error is to reduce the length of your ad copy in the appropriate areas so that it abides by the character length limitations imposed by Google.

You can learn more about this error from Google’s Help section.
