The expression
ImplicitReturnNode returns the type null which is incompatible with the return type mandated by VasilDakov\Shipping\Adap...rInterface::getCities() of VasilDakov\Shipping\Response\GetCitiesResponse.
In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName {
/** @return string */
public function getName();
}
class Name {
public $name;
}
class User implements HasName {
/** @return string|Name */
public function getName() {
return new Name('foo'); // This is a violation of the ``HasName`` interface
// which only allows a string value to be returned.
}

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:
