router.broadcast({ channel }) needs a string channel name; nothing was mirrored.

Since

1.33.0

What happened

broadcast() was called without a channel name, so there is nothing to name the channel after and no channel was opened. Any channel already open is left as it is.

The fix

Pass a channel name that every tab of your application agrees on.

The smallest fix

router.broadcast({ channel: 'orders-v1' });
