In #196, supplier_parties_id became supplier_id, but buyer_parties_id, procuringentity_parties_id and tenderer_parties_id became parties_id. They should all follow the pattern of buyer_id, etc. since the SQL is taking the value from the buyer object, not from the parties object. The remaining parties_id in parties_summary should probably be party_id instead.
