BI Publisher. Report Jobs. Failed to execute event trigger

Hi!

How to find the cause of the error?

::FAILED_TO_EXECUTE_TRIGGER::[INSTANCE_ID=dc1-obiprd02.1512644812180] [JOB_ID=26103926]::

Failed to execute event trigger::

oracle.xdo.servlet.scheduler.ProcessingException: Failed to execute event trigger

at oracle.xdo.servlet.ReportContext.executeEventTrigger(ReportContext.java:643)

at oracle.xdo.enterpriseScheduler.SchedulerJob.execute(SchedulerJob.java:244)

at oracle.xdo.service.scheduling.impl.quartz.QuartzJob.execute(QuartzJob.java:28)

at org.quartz.core.JobRunShell.run(JobRunShell.ja

I try to explore results from this SQL request:

select * from OBIEE_BIPLATFORM.XMLP_SCHED_JOB where job_id = 26103926;

But I found nothing interesting
