Fatal error on Lengow\Connector\Plugin\RulesApplier::aroundApplyRules() with Magento 2.4.4 and above

[xi-ao]

Unfortunately, Magento has changed the signature of applyRules() between 2.4.3 and 2.4.4 which breaks your plugin:

2.4.3
https://github.com/magento/magento2/blob/4c36116dcf878e127059d9be9566a119783583f2/app/code/Magento/SalesRule/Model/RulesApplier.php#L96-L106

2.4.4
https://github.com/magento/magento2/blob/0f9a056c8d83c4f319626b3e56ec52a533999f25/app/code/Magento/SalesRule/Model/RulesApplier.php#L99-L109

$rules is now a simple array and not a Magento\SalesRule\Model\ResourceModel\Rule\Collection anymore.

Any update on this issue? We have too in 2.4.6...

Having the exact same issue after update.

just remove array before $rules like this :

public function aroundApplyRules( RulesApplierModel $subject, Closure $proceed, AbstractItem $item, $rules, bool $skipValidation, $couponCode ) { if ($this->backendSession->getIsFromlengow()) { $rules = $this->ruleFactory->create()->addFieldToFilter('rule_id', ['eq' => 0]); } return $proceed($item, $rules, $skipValidation, $couponCode); }
