Exception in thread "main" java.lang.NullPointerException at net.sf.jasperreports.components.table.fill.TableReport$DetailBandCreator.isEmpty(TableReport.java:812)

[zahirzohair445]

I explored all forums in jasper community for this issue but did not found any solution. I am using TIBCO JasperReports 6.12.2. I designed a template in jasper studio, compiled and previewed, it works fine but when i put the jasper file in a directory in my laravel project and run it, then it shows the error as bellow. any hint or solutions will be very much appreciated.
 

This is the error:
