iOS Question iMQTT - Example MQTTCanvas Error

Hello,

I am using the B4i Build Server, Version: 3.6, iMQTT: 1.0 on my MAC.

I am using the MQTTBroker as my Broker with the example files from:

B4i -- B4i-MQTTCanvas.zip
https://www.b4x.com/android/forum/threads/imqtt-official-ios-mqtt-client.59516/#content

B4j -- MQTTExample.zip
https://www.b4x.com/android/forum/threads/iot-mqtt-protocol.59471/#content

The code is straight from the example zip files except for, username, password and Broker IP address for MQTTBroker.

=============================================================================

I am getting the following two errors:

-- From B4i-MQTTCanvas iPhone app:

This error references the line:
LINE 72: Dim obj As Object = serializator.ConvertBytesToObject(Payload)
