Should publishing and subscribing to an unpermissioned subject cause exceptions?

[darkwatchuk]

Hi, my question is as per the title really.

For example :

If I only have publish and subscribe permissions to the subject "user.alice.debug" and then try and publish to "user.bob.debug" , should this not cause an exception?

using core NATS only, something like ;

await connTokenizedUser.PublishAsync("user.bob.debug", $"debug message sent from alice @ {DateTime.UtcNow:HH:mm:ss}");

The server logs the following error...

  56022 - cid:65 - Publish Violation - Token "alice", Subject "user.bob.debug"

But the client is silent.

Likewise, I would have thought that trying to listen in on user.bob.debug whilst only permissioned for user.alice.debug would also cause an exception.

What's the expected behaviour for the clients in this manner?

Thanks,

-ERR messages comes async so we cant detect at core NATS level. We are logging but not raising an event. looking into that right now...

Edit #745

[mtmk]

just created PR #745

We can't throw exception since error would be sent asynchronously (core publish is fire-forget) but you can with this PR observe the error in an event.

OK, That's great - many thanks.
