Select "New Extract Refresh" and recreate the previous refresh schedules you had setup in Tableau Online

Cause

This occurs in the case where a Data Source was once refreshed by Tableau Bridge but it is now being refreshed by Tableau Online however the Tableau Bridge refresh schedules still exist.
This was a known issue on Tableau Online which is fixed in the current version.
