In this branch, the function will implicitly return null which is incompatible with the type-hinted return Doctrine\DBAL\Connection. Consider adding a return statement or allowing null as return value.
For hinted functions/methods where all return statements with the correct type are only reachable via conditions, ?null? gets implicitly returned which may be incompatible with the hinted type.
Let?s take a look at an example:
interfaceReturnsInt{publicfunctionreturnsIntHinted():int;}classMyClassimplementsReturnsInt{publicfunctionreturnsIntHinted():int{if(foo()){return123;}// here: null is implicitly returned}}

public static function getNativeConnection() : PDO
This check looks for calls to methods that do not seem to exist on a given type.
It looks for the method on the type itself as well as in inherited classes or
implemented interfaces.
This is most likely a typographical error or the method has been renamed.
The expression return Drobotik\Eav\Data...->getNativeConnection() could return the type resource which is incompatible with the type-hinted return PDO. Consider adding an additional type-check to rule them out.
