UH OH!! MqttException (0) : Message not send after user update

[ghost]

Hi,

when i update a user in keycloak, i get this error.
The mqtt broker does not received the message.

15:39:20,487 INFO [stdout] (default task-2) UH OH!! MqttException (0)
15:39:20,488 ERROR [stderr] (default task-2) MqttException (0)

Here is the associated code of the error :

			}
		}

                    </properties>
                </provider>
            </spi>

my Dockerfile

COPY event-listener-mqtt-9.0.0-jar-with-dependencies.jar /opt/jboss/keycloak/standalone/deployments/event-listener-mqtt-9.0.0-jar-with-dependencies.jar
COPY startup-config.cli /opt/jboss/startup-scripts/startup-config.cli
COPY ./imports/keycloak-realm.json /opt/jboss/keycloak/keycloak-realm.json

and my startup-config.cli

embed-server --std-out=echo
/subsystem=keycloak-server/spi=eventsListener/:add
/subsystem=keycloak-server/spi=eventsListener/provider=mqtt/:add(properties={"serverUri" => "tcp://localhost:1883", "topic" => "keycloak"}, enabled=true)
stop-embedded-server

In keycloak, the mqtt logger is selected.
The mqtt run well. I MQTTBox to send message on it.

How can i resolve this error ?

Thanks a lot

Hello,
I think this might be related to #2
It looks like this extension doesn't work well with the keycloak docker image due to some differences with file permissions.
PR #3 might fix your problem. If you could test it and confirm, I'll commit it myself.

Hello,

Apologies for the late followup. I believe the problem is fixed in the latest release - at least it is possible to disable persistence altogether in the settings.

If the problem persists, please reopen an issue.
