Jan 2023 - Process that I followed on Tokyo version that worked successfully to cancel a timer in a flow (catalog request):

 

 

1.  goto table sys_trigger, look for record named flow.fire created in the last few minutes (or the time that your flow action for the timer was started), where the next action field aligns with the timer expiration time (x time in future). Once you identify the target sys_trigger record, set the next action field to the current date and time and save the record.

 

example:

https://<instance-name>.service-now.com/sys_trigger_list.do?sysparm_query=sys_created_onONLast%2045%20minutes%40javascript%3Ags.beginningOfLast45Minutes()%40javascript%3Ags.endOfLast45Minutes()%5Ename%3Dflow.fire

 

2. got table sysevent. ensure the column "process on" is visible in list.  Find the event "flow.fire" where param1 starts with the catalog item name that belongs to the target flow with the timer to be cancelled - set the state field to "processed" and save the record.
