List Not Loading

What Causes This Error

A lead list assigned to a campaign is not populating the hopper with leads. Possible causes: the list status is set to inactive, no leads in the list have statuses matching dial_status_filter, the list is not assigned to the campaign, a lead_filter is too restrictive, or timezone filtering is blocking all leads due to calling hours restrictions.

How to Fix It

• 1 Check list status in Admin > Lists — must be ‘Active’

• 2 Run lead count query: SELECT COUNT(*) FROM vicidial_list WHERE list_id=‘LIST_ID’ AND status IN (‘NEW’,‘NA’)

• 3 Verify list is assigned to campaign: Admin > Campaigns > [Campaign] > Lists

• 4 Check dial_status_filter includes statuses that exist in the list

• 5 Check timezone_filtering — if enabled, all leads may be filtered due to calling hours

• 6 Check lead_filter SQL syntax — errors prevent any leads from loading

• 7 Review hopper fill log: grep ‘hopper’ /var/log/vicidial.log | tail -50

How to Prevent It

Implement lead count monitoring before and during campaigns. Create a pre-campaign checklist that includes lead status distribution review. Test campaigns with small hopper size first to verify leads are loading correctly.
