Uncaught TypeError: get_object_vars()

[multiplehats]

When I try the following query:

$results = Promotion::list();

It throws the following error:

[25-Oct-2024 13:29:08 UTC] PHP Fatal error:  Uncaught TypeError: get_object_vars(): Argument #1 ($object) must be of type object, array given in /Users/jayden/Code/piggy/apps/plugin/vendor/piggy/piggy-php-sdk/src/StaticMappers/Vouchers/PromotionMapper.php:18

Am I missing something?
