Subscription Violation not returned as Subcribe error

[bella-wmi]

Observed behavior

Im expirementing with the auth callout and setting permissions for clients connecting to my nats-server. The following setup is happening:

1. Im creating a client and connecting to the server with the following nats claims:

User claims nats: UserClaimsNats { publish: NatsSubjectPermissions { allow: ["_INBOX.>"], deny: [] }, subscribe: NatsSubjectPermissions { allow: ["allowed_subject"], deny: [] }, jwt_type: "user", version: 2 }

2. The nats connections is created without 'Authorization Violation Errors'
3. Im subscribing to a subject that is not allowed:

let _testsubscribe = nats_client
        .subscribe("this.is.not.allowed")
        .await
        .unwrap();

4. Nats logs returning:

[1] 2024/07/04 09:56:26.024888 [TRC] 172.20.0.6:37146 - cid:619 - <<- [SUB this.is.not.allowed 1]

[1] 2024/07/04 09:56:26.026861 [DBG] 172.20.0.6:37146 - cid:619 - Client connection closed: Client Closed

5. unwarp() call on subcribe is not triggering a panic and the code continues.

Expected behavior

I would expect the subscribe to return an error in this case an the unwrap to trigger a warning.
