validatex | A simple yet powerful data validator for javascript | Validation library

I've a request data transfer object(DTO) which is for accepting POST body of an API. That DTO has an ENUM key of an X entity. I created a custom validation annotation and validate that ENUM exists in my system via its entity repository which returns entity or null based on its existence.

I want to pass that X validated entity to my controller. I don't want to fetch that X entity by ENUM again in my business logic because I've already done that in validation.

I save that entity in a static variable from annotation validator class and access it later when I want that in business logic but if API get hit concurrently, my static variable gets overridden by the second request and when my business logic of the first request fetches X entity, it gets the entity of the second request due to override issue.

I want that X entity object to be scoped inside its own request cycle and destroyed or GC after request completion like other objects. How can I achieve this?
