Subscription not found

Error message

Subscription not found

What it means

getSubscription is produced by createStrictGetter(findSubscription, 'Subscription not found'): it throws when Subscriptions.state.find finds no record with rid matching the chat context. A missing subscription means the current user is not (or not yet) a member of the room in the client's synced state.

Solutions

1. Check isSubscribedToRoom() first and branch (join prompt vs member UI).
2. Use the underlying findSubscription and handle undefined.
3. Ensure the subscriptions store is loaded before rendering member-only affordances.

Example fix

// before
const sub = await chat.getSubscription();

// after
if (!(await chat.isSubscribedToRoom())) {
  // not a member: preview UI or joinRoom() first
  return;
}
const sub = await chat.getSubscription();

if (!(await chat.isSubscribedToRoom())) {
  // previewing without membership — join first or render preview UI
  return;
}
const sub = await chat.getSubscription();

When it happens

Trigger: Calling getSubscription while previewing a public channel the user has not joined, before subscriptions finish syncing after login, after being removed from the room while its UI is still open, or for a logged-out/anonymized state.

Common situations: Public channel preview flows, notification deep-links into unjoined rooms, team channels the user was kicked from mid-session, race at app startup.
