Error message

No data returned.

What it means

Raised inside php artisan koel:doctor's service-integration checks. The doctor sends a real Last.fm GetArtistInfoRequest('Pink Floyd'); when the connector's dto() comes back null it means the API responded but with a payload that didn't deserialize into the expected DTO - almost always an error response (e.g. 'invalid api key') rather than actual artist data. The doctor collects it and reports the Last.fm integration as failing; it is diagnostic output, not an application crash.

Solutions

1. Set valid LASTFM_KEY and LASTFM_SECRET in .env (from last.fm/api/account/create)
2. Run php artisan config:clear so new keys are picked up, then rerun koel:doctor
3. Verify outbound access from the server: curl 'https://ws.audioscrobbler.com/2.0/' and check the raw response
4. Treat the failure as non-fatal if you don't use Last.fm scrobbling - other doctor checks proceed independently

// Skip or short-circuit Last.fm work when credentials are absent
if (!config('koel.lastfm.key') || !config('koel.lastfm.secret')) {
    return; // integration intentionally unused
}

$dto = app(LastfmConnector::class)->send(new GetArtistInfoRequest($artist))->dto();

try {
    $dto = $connector->send(new GetArtistInfoRequest('Pink Floyd'))->dto();
} catch (Throwable $e) {
    // network/HTTP-level failure: report and degrade gracefully (scrobbling off)
    Log::warning('Last.fm unreachable', ['error' => $e->getMessage()]);
    $dto = null;
}

When it happens

Trigger: LASTFM_KEY/LASTFM_SECRET missing, invalid, or revoked in .env; Last.fm returning an error JSON (no artist object to map); outbound HTTPS to ws.audioscrobbler.com blocked by firewall/DNS.

Common situations: Fresh installs where Last.fm env vars were never set; keys rotated or revoked; server egress restrictions; stale config cache keeping old keys after .env changes.
