We are having a problem with one of our new reports.
This report shows data for some periods of time in an excel file.
If we generate short periods, like one to three months, it works perfect.
But if we generate a longer period, like one o half of a year, shows this error: net.sf.jasperreports.engine.JRRuntimeException: java.io.IOException: The handle is invalid.
I do not have access to the logs of the environment in which it is generated since it is a productive environment
Thanks in advance.
