Cannot assign float to property System::$_memTotal of type int

I have a new install of FreePBX 17.0.24 on a Pi 4 running Bookworm. When I load the dashboard I get this constat popup in red:

Cannot assign float to property System::$_memTotal of type int
File:/var/www/html/admin/modules/dashboard/classes/phpsysinfo/includes/to/class.System.inc.php:917

Not sure what the error is. I followed the install instructions at GitHub - playfultechnology/RasPBX: Installation of Asterisk and FreePBX GUI on Raspberry Pi to the letter

PHP log file should have a full error message. You should report bugs here: GitHub ยท Where software is built
