[omnidisc] could not subscribe to gateway events

Error message

[omnidisc] could not subscribe to gateway events

What it means

During store init, the store subscribes to backend events (`omnidisc://dispatch`, `omnidisc://status`, `omnidisc://upload`, `omnidisc://decrypted`) via Tauri's listen(). If any listen() call rejects (event not registered, app handle unavailable) the store resets `initialized = false`, logs this warning, and aborts init — the gateway will never be connected for any instance, so all realtime features stay dead until init is retried.

Solutions

1. Check errorText(e) to see which listen() call failed
2. Ensure the app is running inside the Tauri webview (not a plain browser tab) and the event-emitting Rust side is initialized before the frontend subscribes
3. Retry init after the runtime is ready — initialized was reset to false so a re-init is possible
4. Verify frontend event names match the backend emit strings exactly

// only init inside the Tauri runtime
if (!("__TAURI_INTERNALS__" in window)) { console.warn("not in Tauri runtime"); return; }

try {
  offDispatch = await listen("omnidisc://dispatch", ...);
  offStatus = await listen("omnidisc://status", ...);
} catch (e) {
  initialized = false;
  console.warn("[omnidisc] could not subscribe to gateway events", errorText(e));
  return;
}

When it happens

Trigger: Calling the store's init/connect flow when one of the four listen<T>("omnidisc://…") promises rejects — typically the Tauri runtime not ready, plugin not initialized, or running outside a Tauri window (e.g. plain browser during dev).

Common situations: Developing in a browser without the Tauri runtime so invoke/listen are stubbed or absent; app updated with renamed events while a stale backend runs; very early subscription before the app setup completes.
