Error saving template

When I try to save a template I get the following error:

Call to undefined method Joomla\Component\GMapFP\Administrator\Table\TemplateTable::getCurrentUser()

on line

JROOT/administrator/components/com_gmapfp/src/Table/TemplateTable.php:77

Joomla 5.4.1

GmapFP version: 4.10.19. You modified the code when you solved my previous problem. See: Frontend form forum entry.

It works if I replace

$userId = $this->getCurrentUser()->id;

with

$userId = Factory::getApplication()->getIdentity()->id;

in the check() function of the TemplateTable.php file
