The method setInput() does not exist on Coco\SourceWatcher\Core\Step. It seems like you code against a sub-type of Coco\SourceWatcher\Core\Step such as Coco\SourceWatcher\Core\Extractor.
                                                                                   (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-call   annotation
