I can't use zigbee2mqtt

Your HA gateway can support zigbee2mqtt add-on, but I have encountered error when I try to add it in.

Please make sure that you are setting the correct port: dev/ttyUSB1, also make sure your repository is GitHub - Zengzisheng/hassio-zigbee2mqtt-1: Official Zigbee2MQTT Home Assistant add-on and try it again.
