Architect Script Block: 404 on /v2/architect/scripts during bulk export metadata validation

{"error_code": 404, "message": "Script not found: script_id_998877"}

Running a bulk export job for digital channel transcripts (WhatsApp/Messenger) in Genesys Cloud v2024.02 (London region). The job fails when attempting to validate the associated Architect script block for metadata enrichment. The script ID exists in the UI and returns 200 via GET, but the export service returns 404. Is there a permission scope mismatch for the service account used in the export job?
