Scheduled Recurrence Trigger Added to the Flow in Workflow St — Flow Never Fires at Scheduled Time

[Gintarevvv]

Hi Community,

I'm hoping someone can help me troubleshoot an issue with a scheduled trigger in Workflow Studio that is not firing at the expected time.

Setup:

• ServiceNow Flow with a Recurrence trigger
• Trigger type: Recurrence
• Time zone: Use System Time Zone
• Start date and time: 2026/x/x 06:30:00
• Repeat: Time interval — every 08:00:00
• End: No end date

What I did:

1. Created a new Trigger Definition record 
2. Deleted the old trigger from the flow 
3. Added the new trigger back to the flow
4. Deactivated and re-activated the flow

Problem: The flow is not firing at the scheduled time at all. After investigation I found that:

• The sys_flow_trigger_auto_script record was never automatically created after re-adding and activating the trigger

Questions:

1. Is sys_flow_trigger_auto_script supposed to be auto-generated when a Recurrence trigger is activated on a flow?
2. If it is missing — what is the correct and supported way to recreate it without breaking the flow?
3. Is there a known issue or KB article related to sys_flow_trigger_auto_script not being created after a trigger is deleted and re-added in Flow Designer?

Any guidance would be greatly appreciated! Thank you.

Hey @Gintarevvv 

The short answer is yes the sys_flow_trigger_auto_script record should be auto-generated when the schedule based flow is activated. There are a couple articles related to the flows not triggering at the expected time but not the specific issue of the record not being created at all. Linked below are the articles I found.

I tend to recreate a flow if it has an issue as detrimental as that. I've only had a few one-off scenarios that required that but it can be an annoying process depending on how complex the flow is. I recommend opening a support ticket if it happens again so that there can be more investigation into the root cause.

Thank you, the flow was copied and recreated with a new trigger because the trigger and trigger execution records were missing, and those records should be created automatically by ServiceNow. I also found a start time mismatch between sys_flow_trigger_auto_script and sys_flow_enhanced_timer_trigger. After correcting the time slots so they matched, the trigger fired successfully. I will monitor it now, and if it continues working as expected.
