Possible cause #1

This problem occurs when you have URL Builder enabled but are not using redirected URLs, and you include the Click Through URL column header in your bulk sheet. This header is reserved for clients using redirects. If you include this column when not using redirects, you’ll encounter the error message above.

Possible cause #2

This problem can also occur when you have URL Builder enabled and you're using redirected URLs. Typically, including the URL in the Click Through URL column should result in successful processing, but if you see this error, it can mean that you have spaces in the redirect URL specified in URL Builder.

Spaces are not allowed in a redirected URL because they can prevent the redirect from being established altogether. This can cause the system to not recognize that you are using redirects and thus throws this error message when you attempt to load URLs via the Click Through URL column.

Possible cause #1 fix

Simply go to your bulk sheet and change the Click Through URL column header to read Destination URL. Next re-upload your bulk sheet (or just the affected rows, being sure to remove the Result column), and the problem should be resolved.

Possible cause #2 fix

Just follow these steps:
 

1. Navigate to Admin > Revenue tab > URL Builder.
    
2. Check through the redirect URL specified in each of the publisher sub-tabs to make sure there are no extra spaces.
    
3. Once you have removed all of the extra spaces in each publisher sub-tab, click Save to establish the general redirect setting. The issue should now be fixed, and loading URLs via the Click Through URL column should process successfully.
