Full Privacy import fails validation when export contains podcasts/audiobooks with null metadata

[Rolucious]

Description

When importing extended streaming history (Streaming_History_Audio_*.json files), the import fails with validation errors if the export contains podcast or audiobook entries that have null values for master_metadata_track_name and spotify_track_uri.

Steps to Reproduce

1. Request extended streaming history from Spotify (Full Privacy Data)
2. Receive files named Streaming_History_Audio_YYYY-YYYY_X.json
3. Attempt to import via Settings → Full Privacy import
4. Import fails with validation errors

Error Output

{
  "expected": "string",
  "code": "invalid_type",
  "path": [9898, "master_metadata_track_name"],
  "message": "Invalid input: expected string, received undefined"
}

Root Cause

Spotify's export includes podcast/audiobook entries like this:

{
  "ts": "2024-01-15T10:00:00Z",
  "ms_played": 120000,
  "spotify_track_uri": null,
  "master_metadata_track_name": null,
  "master_metadata_album_artist_name": null,
  "episode_name": "Podcast Episode Title",
  "spotify_episode_uri": "spotify:episode:xxxxx"
}

The current validation in fullPrivacyFileSchema requires all records to have non-null master_metadata_track_name and spotify_track_uri, which causes the entire import to fail when any podcast/audiobook entries are present.

Expected Behavior

The importer should skip records that are podcasts/audiobooks (identifiable by null track metadata but present episode metadata) rather than failing the entire import.

Suggested Fix

In apps/server/src/tools/importers/full_privacy.ts, filter out records where master_metadata_track_name is null before validation, or make the schema more lenient and filter during processing.

Workaround

Pre-process the JSON files to filter out records where master_metadata_track_name is null:

import json
data = json.load(open('Streaming_History_Audio_*.json'))
cleaned = [r for r in data if r.get('master_metadata_track_name') is not None]
json.dump(cleaned, open('cleaned.json', 'w'))

Environment

• Your Spotify version: latest (Dec 2025 image)
• Spotify export format: Extended streaming history (2025 format)
