			1 ignored issue – show Bug introduced 2021-11-25 10:27 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$post` is correct as `self::postHeaders->find(...ion(...) { /* ... */ })` targeting `DusanKasan\Knapsack\Collection::find()` seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...
