Problems with publishMQTT after Update from OH2.4 to 2.5.0.M5

Hi @J-N-K. Thanks for replay :slight_smile:
I think, it may be a cause. I publish commands via:

val GetCommandJSON = [ String command |
  String::format("{\"command\":\"%s\",\"time\":%d,\"initiator\":\"localApp\"}", command, now.millis / 1000)
]

rule "RoombaCleanStartReceivedCommand"
when
  Item RoombaCleanStart received command ON
then
  val roomba = getActions("mqtt", "mqtt:broker:roomba")
  if(roomba !== null) {
    roomba.publishMQTT("cmd", GetCommandJSON.apply("start"))
  } else {
    logWarn("RoombaBroker", "Roomba broker returned no actions")
  }
end

I will setup HiveMQ CLI next days to be more precise where the error may be.

EDIT: Hello @J-N-K,
small update: I’ve created an command channel as

      Type string : command  "Command" [ commandTopic = "cmd" ]

as well item

String   RoombaSendCommand    "Roomba Command [%s]" { channel="mqtt:topic:roomba:state:command" }

and modified a rule to

rule "RoombaCleanStartReceivedCommand"
when
  Item RoombaCleanStart received command ON
then
  val cmd = String::format("{\"command\":\"start\",\"time\":%d,\"initiator\":\"localApp\"}", now.millis / 1000);
  RoombaSendCommand.sendCommand(cmd);
  logInfo("RoombaCleanStartReceivedCommand", cmd);
end

Now the situation is a little bit different: It happen still nothing, but there is no error message in log anymore. Trying to send something with publishMQTT, leads immediatly in

com.hivemq.client.mqtt.exceptions.MqttSessionExpiredException

I think, we have a bug in actions.

Kind regards,

Alexander
