The expression $this->firstOfPropertyNames($names); of type string|array|null adds the type array to the return on line 129 which is incompatible with the return type declared by the interface Jkphl\Micrometa\Ports\Item\ItemInterface::firstOf of type string|string[].

Are you sure the assignment to $value is correct as $this->getPropertyValueOrValueList($name) (which targets Jkphl\Micrometa\Ports\Item\Item::getPropertyValueOrValueList()) seems to always return null.

            if ($value !== null) {

The parameter $name is not used and could be removed.
