__init__() takes 2 positional arguments but 3 were given

I’ve just tried installing on a RPi 3B+ running Ubuntu Server 18.04.3 from here. Following the instructions for installation of bt-mqtt-gateway, I encounter the issue shown below:

(.venv) ubuntu@ubuntu:~/bt-mqtt-gateway$ sudo ./gateway.py -d 2019-10-16 10:27:29,252 INFO bt-mqtt-gw gateway.py:61:<module> - Starting 2019-10-16 10:27:29,254 DEBUG bt-mqtt-gw.mqtt mqtt.py:30:init - Setting LWT to: lwt_topic 2019-10-16 10:27:29,592 INFO bt-mqtt-gw.workers.miflora miflora.py:23:_setup - Adding 11 miflora devices 2019-10-16 10:27:29,592 DEBUG bt-mqtt-gw.workers.miflora miflora.py:25:_setup - Adding miflora device ‘rosemary’ (C4:7C:8D:66:2F:D0) Traceback (most recent call last): File “./gateway.py”, line 67, in <module> manager.register_workers(global_topic_prefix).start(mqtt) File “/home/ubuntu/bt-mqtt-gateway/workers_manager.py”, line 88, in register_workers command_timeout, global_topic_prefix, **worker_config[“args”] File “/home/ubuntu/bt-mqtt-gateway/workers/base.py”, line 7, in init self._setup() File “/home/ubuntu/bt-mqtt-gateway/workers/miflora.py”, line 28, in _setup “poller”: MiFloraPoller(mac, BluepyBackend), File “/usr/local/lib/python3.6/dist-packages/miflora/miflora_poller.py”, line 37, in init self._bt_interface = BluetoothInterface(backend, adapter) TypeError: init() takes 2 positional arguments but 3 were given

My config is the same as what I had running and working on an Intel NUC running Ubuntu server, so it shouldn’t be an issue with my config:

Not sure what has gone wrong, please help!
