KMQTT BROKER - topicAliasMaximum set to 0 even when topicAliasMaximum is set on client.

[nishankhadka09]

connAck packet -

MqttConnAck{reasonCode=SUCCESS, sessionPresent=false, restrictions=MqttConnAckRestrictions{receiveMaximum=1024, maximumPacketSize=32768, topicAliasMaximum=0, maximumQos=EXACTLY_ONCE, retainAvailable=true, wildcardSubscriptionAvailable=true, sharedSubscriptionAvailable=true, subscriptionIdentifiersAvailable=true}}

The topicAliasMaximum is 0 in the connAck message, but the client connection snippet is :

(mqttClient as Mqtt5Client?)?.toAsync()?.connectWith()?.restrictions()
            ?.topicAliasMaximum(65535)?.applyRestrictions()?.cleanStart(true)?.send()

Shouldn't the connAck have topicAliasMaximum of not 0??

Client disconnects once I publish to two or more topics saying - Exception while decoding PUBLISH: topic alias must not be 0
