The payload you’re seeing is the full LoRaWAN packet for a downlink. This has been published by TTN on the MQTT <AppID>/devices/<DevID>/events/down/sent topic. So, it’s not the uplink you’re looking for.
Also, it seems you’re using the deprecated TTN Node-RED library. Don’t use that for new developments, see Why is Node-RED integration no longer supported?
