The sys.files variable is indeed a default variable in the input node, primarily used for handling file uploads like images. However, there is no specific documentation or information available in the repository that explains why sys.files cannot be accessed or referenced in nodes other than the input node. It might be a design choice or a technical limitation, but this isn't explicitly documented in the available resources ^[1][2].
