I am using Basic IDE to publish MQTT messages. My script works fine and the broker is able to receive all the published messages. However, it keeps showing this error message each time the code is being executed. You have any idea what is this and how can I get rid of it?
Operation Failed: MQTT “PUBLISH”, “/Demo/Flexy/” + SerNum$ + “/MODBUS/AI0”, value_AI1$, 1,0
