Hello @ilnytskyi,

Thanks for the report and collaboration!

We have reviewed the codebase of the below file:

magento2/app/code/Magento/CatalogRule/Model/Rule/Condition/ConditionsToSearchCriteriaMapper.php

Lines 85 to 89 in 0b488dd

	if ($condition->getType() === CombinedCondition::class) {
	return $this->mapCombinedConditionToFilterGroup($condition);
	} elseif ($condition->getType() === SimpleCondition::class) {
	return $this->mapSimpleConditionToFilterGroup($condition);
	}

And compare the changes made in the PR.

$condition->getType() === CombinedCondition::class: This code compares the result of the getType() method of the $condition object with the fully qualified class name of CombinedCondition. It checks if the type returned by getType() is exactly the same as the CombinedCondition class name.

And

$condition instanceof CombinedCondition: This code checks if the $condition object is an instance of the CombinedCondition class or any of its subclasses. It is a more direct way to check the type of an object. Which seems relevant. Hence confirming this issue for further processing.

Thanks
