Documentation Bug introduced by
It seems like $this->hydrator->hydrateRow() of type false is incompatible with the declared type null|object of property $current.

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.

Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..

The condition is_array($this->current) is always false.
