Subreport in JasperStudio and Laravel

Good afternoon! I have a question about using subreports in jasperstudio using Laravel. I created a report and a subreport, both located in the same folder, and when running the code I receive an error message stating that the subreport was not found. I've already tried creating a parameter called SUBREPORT_DIR and passing the absolute path of the subreport and it still doesn't find it. Have you ever experienced something like this using JasperStudio 6.17, Laravel 5.7 and PHP 7.4. Below is the excerpt of the code that feeds the parameter: $subRelatorio = base_path('public/reports/relatorios/progressao/subreport.jasper');

     $parameters = [
         'p_anoLetivo' => $request->ano_letivo,
         'pccriterio' => $criterio,
         'username' => $user->name,
         'SUBREPORT_DIR' => $subReport
     ];

And the excerpt from Jasper's main report where the subreport is called: <reportElement x="360" y="22" width="390" height="50" uuid="bfa5ab8e-641c-4ddb-8345-7e607b792abf"/> <subreportParameter name="pidAlunoProgressao"> <subreportParameterExpression></subreportParameterExpression> </subreportParameter> <subreportParameter name="panoMatriculaProgressao"> <subreportParameterExpression></subreportParameterExpression> </subreportParameter> <connectionExpression></connectionExpression> <subreportExpression></subreportExpression>

Any help will be appreciated.

Thank you, Carlos Henrique
