The function of extracting events into pdf is not functioning properly.

Work environment

Expected behavior

event -> Download as -> Pdfexport
Events are extracted as pdf.

Actual behavior

event -> Download as -> Pdfexport
The generated pdf has a file size of 0.

Steps to reproduce the behavior

event -> Download as -> Pdfexport
Due to the large number of Galaxies the event, it occurs when the "General information" in the PDF file is over 1 page.
(For example, you have 80 Galaxies in an event.)

Start in PyMISP/pymisp/tools/reportlab_generator.py at convert_event_in_pdf_buffer and export_flowables_to_pdf, following the ReportLab LayoutError shown in the issue. Reproduce the event PDF export with enough Galaxies for the General information section to exceed one page. Done means the export produces a non-empty PDF without this layout error.
