I solved using this code:

```python
logger = system.util.getLogger("myLogger")
 logger.info("Iniciando la ejecución de doGet")

 path = "RENEW/PLANILLAS/PREVENTIVA_PLANILLA/PLANILLA_MANT_PREVENTIVO_E"
 params = {
     "ID_PREVENTIVA": 6228,
     "CATEGORIA": "INFRAESTRUCTURA NECESARIA"
 }

 try:
     report_bytes = system.report.executeReport(
         path=path,
         project='Mantenimiento_vn',
         parameters=params,
         fileType='pdf'
     )
    return {
        "contentType": "application/pdf",
         "headers": {
             "Content-Disposition": "inline; filename=preventivo_e.pdf"
         },
         "bytes": report_bytes
     }

 except Exception as e:
     logger.error("Error al generar el reporte: " + str(e))
     return {"error": "Error al generar el reporte: " + str(e)}

```
