Where is the $white_list to stop OpenEMR SQL Escaping ERROR:

Hi @sunsetsystems
Clinical Rules is throwing an error because the variable $s is being passed as an empty string.
This has a cascade effect on the system. The doc block is good information but does not lead me to where the white list is created. I see that the clinical rules have no direct relationship to formdata.inc.php. I was hoping you could point me in the right direction.

OpenEMR v7.0.0 (2)

Ubuntu 22.04
