Hi, I am using psalm heavily and have reached a situation where I can have

public function doSth(EntityInterface|Proxy $entity): bool
{
    //....
}

All my entities implement the EntityInterface, because I enforce that every entity has a getId() method.

Obviously, my psalm now cries

Method Doctrine\Common\Proxy\Proxy::getId does not exist

Is there some adviced way to make Proxies type-safe? Thank you

Why do you typehint for proxy? You should not need this.

Correct typehint is EntityInterface|(EntityInterface&Proxy)

Thank you very much- I did not know of the intersection types.
