Last.fm RSS is disabled due to the lack of <a href="https://

Error message

Last.fm RSS is disabled due to the lack of <a href="https://docs.rsshub.app/deploy/config#route-specific-configurations">relevant config</a>

What it means

Thrown by the Last.fm loved-tracks route (deprecated) when the Last.fm integration is not configured. The guard `!config.lastfm || !config.lastfm.api_key` fails and the route refuses to run, pointing at the route-specific config docs. An API key is mandatory because the route calls the audioscrobbler API directly.

Solutions

  1. Obtain an API key from https://www.last.fm/api/account/create and set LASTFM_API_KEY in RSSHub config.
  2. Restart RSSHub after setting the env var so config.lastfm.api_key is populated.
  3. Confirm config.lastfm is an object (not falsy) in your config file.

Example fix

// config (env)
// before
LASTFM_API_KEY=
// after
LASTFM_API_KEY=<your_key>
Defensive patterns

Strategy: validation

Validate before calling

if (!process.env.LASTFM_API_KEY) {
  throw new Error('LASTFM_API_KEY missing — create one at https://www.last.fm/api/account/create');
}

Type guard

const hasLastfmConfig = (c: { lastfm?: { api_key?: string } }): boolean =>
  Boolean(c.lastfm && c.lastfm.api_key);

Try / catch

try { await rsshub('/lastfm/loved/' + user); }
catch (e) {
  if (/disabled due to the lack/.test(e.message)) return configureAndRetry();
  throw e;
}

Prevention

When it happens

Trigger: RSSHub deployed without a LASTFM_API_KEY (or the config block absent). Any request to the loved-tracks route triggers the throw before the API call.

Common situations: Fresh install without setting LASTFM_API_KEY in env/config; key removed during config cleanup; or running in an environment that strips the config block.
