Problem summary
The Trade Desk advertiser stops delivering rows while the data source keeps running successfully and other advertisers on the same report continue to land data. In Funnel the affected advertiser shows a flat gap: rows that used to arrive daily drop to zero from a certain date onward.
Error message or symptoms
You may see one or more of the following:
The affected advertiser returns zero rows from a certain date onward
Other advertisers on the same report template continue to return data
The data source authenticates and completes its runs with no connection error and no failed downloads
When does this occur
You have a The Trade Desk source that includes more than one advertiser
Only one advertiser stops returning data while others continue
Campaigns for the affected advertiser may be paused, ended or disconnected from the report schedule in The Trade Desk
Root cause
Suspected: The Trade Desk is returning an empty report for that advertiser. This is not a Funnel connection or credential problem, because the source authenticates and completes its runs. It is also not specific to one report template, because a different advertiser on the same template continues to return full data.
Solution
In The Trade Desk platform, confirm that the affected advertiser still has campaigns that were live during the affected dates. If the campaigns were paused or ended, The Trade Desk returns no rows for that period and there is no data for Funnel to fetch.
If campaigns are active but data still does not arrive, rebuild the report schedule directly in The Trade Desk so the advertiser is included again. A configuration change in Funnel alone does not restore data when the report itself no longer includes the advertiser.
After The Trade Desk returns data again for the advertiser, Funnel picks it up on the next scheduled run.
