To Reproduce
Steps to reproduce the behavior:

1. Composer require phpjasper on laravel
2. create a report with subreports on jasper studio
3. try accessing the report using the documentation giving
4. ensure you change the code in the output function to "return $this->the_command" in /vendor/cossou/jasperphp/src/JasperPHP/JasperPHP.php
5. See error

Expected behavior
It was expected to create the pdf report as it was working perfectly in Jasper Studio but it did not. So I decided to output the error and that was when I got the error above

Works for me use the same compiller for all .jrxml reports/sub_reports.
Example:
sh vendor/geekcom/phpjasper/bin/jasperstarter/bin/jasperstarter compile /var/www/html/reports/child_subreport_1.jrxml
And after do the same with de "dad" report
sh vendor/geekcom/phpjasper/bin/jasperstarter/bin/jasperstarter compile /var/www/html/reports/dad_report.jrxml

Same error here. I had to modify a subreport with JasperSoft, and it must have changed the version without me noticing. So I ran the compile command on the JRXML, and it worked.
