What causes "[player] failed saving spotify heartbeat_enabled" in tonhowtf/omniget?

Check the logged cause (transport vs storage)

[player] failed saving spotify heartbeat_enabled

Error message

[player] failed saving spotify heartbeat_enabled

What it means

Non-fatal warning: persisting the new heartbeat_enabled value via study:music:spotify:settings:set failed. The in-memory flag is already applied and heartbeat start/stop proceeds regardless, but the preference may not survive restart.

Solutions

Check the logged cause (transport vs storage)
Verify the backend implements study:music:spotify:settings:set
Retry the save or re-toggle the setting once the backend responds
Surface a 'preference not saved' hint to the user if persistence keeps failing

Example fix

// before
catch (e) {
  console.warn("[player] failed saving spotify heartbeat_enabled", e);
}
// after
catch (e) {
  console.warn("[player] failed saving spotify heartbeat_enabled", e);
  this._spotifySettingsSaveFailed = true; // re-attempt on next toggle
}

Defensive patterns

Strategy: try-catch

Validate before calling

if (typeof value !== "boolean") throw new TypeError("heartbeat_enabled must be boolean");

Try / catch

try {
  await pluginInvoke("study", "study:music:spotify:settings:set", { heartbeat_enabled: value });
} catch (e) {
  console.warn("[player] failed saving spotify heartbeat_enabled", e);
  queueSaveRetry({ heartbeat_enabled: value });
}

Prevention

Apply the in-memory change immediately, persist asynchronously
Queue a retry when persistence fails so the preference eventually saves
Notify the user if a preference could not be persisted
Verify backend implements the settings:set command before release

When it happens

Trigger: pluginInvoke("study", "study:music:spotify:settings:set", { heartbeat_enabled }) rejects — backend unavailable, command missing, or storage write error.

Common situations: Study plugin not running during the toggle, backend missing the settings:set command, or read-only/full settings storage.
