Description

Hello! I use ramsey/uuid library in my code, and when I run my test on PHP 8.1 beta1 I'm getting the following error:

PHP Fatal error:  During inheritance of ArrayAccess: Uncaught Return type of Ramsey\Collection\AbstractArray::offsetGet($offset) should either be compatible with ArrayAccess::offsetGet(mixed $offset): mixed, or the #[ReturnTypeWillChange] attribute should be used to temporarily suppress the notice
