Issue/Introduction

When I schedule the report I get an email with an empty file and I get the following error:
 
JasperReports Server encountered an error while generating this report. Please contact your administrator.
 


If looking in the logs we can see the following error:

2019-01-04 06:00:31,079 ERROR HibernateDaoImpl,quartzScheduler_Worker-6:111 [] - ************** HibernateDaoImpl.executeWriteCallback EXCEPTION **********

Deleting and recreating the scheduled report works only temporarily.

Resolution

Schedule the report at a different time, for example 1 hour before or after the previous schedule. This would avoid any potential report misfires and solve the problem.

Also applies when no report notification is sent out.
