The property $state was declared of type integer, but substr($accessKey, $startPosition, 2) is of type string. Maybe add a type cast?

It seems like \DateTime::createFromFormat('ymd H:i:s', substr($accessKey, $startPosition, 4) . '01 00:00:00') can also be of type false. However, the property $generatedAt is declared as type object<DateTime>. Maybe add an additional type check?
