What causes "[study-music] sponsorblock lookup failed:" in tonhowtf/omniget?

Check the logged `err` for network vs backend-command errors.

[study-music] sponsorblock lookup failed:

Error message

[study-music] sponsorblock lookup failed:

What it means

Lookup of SponsorBlock segments for the current YouTube video (via $lib/study-bridge's studyYoutubeSponsorblock) failed; the store logs a warning and continues with empty sponsor segments. Playback is unaffected; only skip-ad/sponsor automation is disabled for that video.

Solutions

Check the logged `err` for network vs backend-command errors.
Retry the lookup after a short delay; SponsorBlock outages are usually transient.
Confirm the backend's SponsorBlock integration is enabled and the service URL is reachable.
Treat empty segments as expected behavior — verify youtubeSponsorBlockSegments stays empty only for videos with no segments.

Defensive patterns

Strategy: try-catch

Validate before calling

if (!videoId || typeof videoId !== "string") return; // skip lookup entirely

Type guard

function hasSegments(res: unknown): res is { segments: unknown[] } {
  return typeof res === "object" && res !== null && Array.isArray((res as any).segments);
}

Try / catch

try {
  const res = await studyYoutubeSponsorblock({ videoId });
  if (this.youtubeCurrentVideoId !== videoId) return;
  this.youtubeSponsorBlockSegments = res.segments ?? [];
} catch (err) {
  console.warn("[study-music] sponsorblock lookup failed:", err);
  this.youtubeSponsorBlockSegments = [];
}

Prevention

Treat SponsorBlock as optional: always default segments to empty on failure.
Add a timeout to the lookup so slow SponsorBlock responses don't block playback.
Drop stale lookups when the current video changes (already done via videoId check).
Cache segments per videoId to reduce repeat calls.

When it happens

Trigger: Dynamic import of $lib/study-bridge or studyYoutubeSponsorblock({videoId}) rejecting — backend sponsorblock command missing, network failure to the SponsorBlock service, or IPC error.

Common situations: SponsorBlock API outage or rate limiting on the backend; offline/poor network; stale videoId (video changed mid-lookup, which the code also guards via youtubeCurrentVideoId check); plugin bridge not compiled in.
