Error message

Subscription not found

What it means

unreadMessages requires the caller to have a subscription with a last-seen timestamp in the message's room: Subscriptions.findOneByRoomIdAndUserId(rid, userId)?.ls. A missing subscription (or one without ls) throws Meteor.Error('error-subscription-not-found', 'Subscription not found') - without ls the server cannot compute the unread window.

Solutions

1. Ensure the user joined the room (subscription exists) before enabling mark-unread
2. Refresh subscriptions after kick/remove events and hide such rooms
3. Join the room first when acting on previewed public channels

Example fix

// before
Meteor.call('unreadMessages', { _id: messageId }); // not a member

// after
const sub = Subscriptions.findOne({ rid: message.rid });
if (sub) {
  Meteor.call('unreadMessages', { _id: messageId });
} else {
  Meteor.call('joinRoom', message.rid);

const sub = await Subscriptions.findOneByRoomIdAndUserId(message.rid, userId);
if (!sub?.ls) {
  return; // no membership/last-seen: unread is not applicable
}
await unreadMessages(userId, { _id: message._id });

Meteor.call('unreadMessages', { _id }, undefined, (err) => {
  if (err?.error === 'error-subscription-not-found') {
    hideRoomAndResync(message.rid); // user is not a member anymore
  }
});

When it happens

Trigger: Marking a message unread in a room the user has no subscription for: never joined, was removed, or only previewed a public channel without joining; calling with a message id belonging to a room the account cannot see.

Common situations: Stale UI offering unread for rooms the user was removed from; directory/preview flows where the room is visible but not joined; race between joining and acting.
