Broadcasting not emitting events

I am having some issues getting broadcasting to work locally. I have created a very permissive migration (see screenshot) to test.
It follows the official Supabase documentation on how to setup broadcasting and, for confirmation that it is actually triggering the function, I also add a record to the

broadcast_debug_log

broadcast_debug_log

table.

When I run my application, I can confirm that there are records being inserted in the table, but no broadcast events are emitted.
I am using the

realtime inspector

realtime inspector

service_role

service_role

to subscribe to the channel

topic:worker_run_tracking_changes

topic:worker_run_tracking_changes

and I see the

postgres_changes

postgres_changes

events coming in but no

broadcast

broadcast

events

I also have a

realtime-listener.js

realtime-listener.js

script (see screenshots as well) that listens for events that is also not receiving any of the

broadcast

broadcast

messages.
The only messages I see are ones that I manually trigger through another JS script:

  const payload = {
    msg: "🚀 Hello from broadcaster!",
    time: new Date().toISOString(),
    pid: process.pid,
  };

  const result = await channel.send({
    type: "broadcast",
    event: "manual_test",
    payload,
  });
  console.log("📬 Broadcast result:", result);

  const payload = {
    msg: "🚀 Hello from broadcaster!",
    time: new Date().toISOString(),
    pid: process.pid,
  };

  const result = await channel.send({
    type: "broadcast",
    event: "manual_test",
    payload,
  });
  console.log("📬 Broadcast result:", result);

What might I be doing wrong? Why isn't the broadcasting working?
