National Drug Data File (NDDF) is a BioPortal ontology that KG‑Bioportal has not transformed to KGX. This ontology is only available under a license we do not hold (typically a UMLS licence), so BioPortal does not serve its source file to the pipeline. It is not transformed by design, and there is nothing to retry.
