Error description

  • The MQTT Publish node will always disconnect the client when
    local environment overrides are being used to specify the
    connection URL at runtime for example:
    .
    SET OutputLocalEnvironment.Destination.MQTT.Output.URL =
    'tcp://localhost:1883';
    .
    The client should only be disconnected if the URL being used is
    different to the one currently being used.

Problem conclusion

  • The MQTTPublish node now only disconnects if the URL does not
    match the one currently associated with the current connection.
    Additionally to provide further fault tolerance to intermittent
    connection issues the MQTTPublish node will now attempt a single
    inline retry when it receives a broken connection error from an
    attempt to publish a message.
