Error in Line 60 "foreach() argument must be of type array|object, null given in C:\floorfy-dl.php on line 60"

[Connerkurtz]

Title says it all. PHP and cUrl are loaded and working (allegedly), but receiving a null in line 60 when running:
php floorfy-dl.php https://floorfy.com/tour/1990145

I'm new to PHP, so any help would be greatly appreciated.

It is generating a CFG.json file each time, but the file is blank.

Full Output:
