MQTT no attribute '_InterfaceMQTT__device_id'

[koto60]

I am trying to set up MQTT but I get a weird error. I have tried looking around for answers, but I cannot find anything.

My config is:

mqtt:
  use_mqtt: True                # default=False. Set True true, to enable mqtt
  server: "localhost"     # No defaults for server
  port: 1883                     # default=8883 for tls, 1883 else (tls must be "" then !!!!!)
  login: ""                      # your mqtt user
  password: ""                   # password for mqtt user
  tls: ""                        # filename including path to your ca.crt. If not used, must be set to "" !!!!
  device_id: "picframe"  

I get the error:

INFO:start.py:starting ['/home/pi/.local/bin/picframe']
INFO:model.Model:Open config file: /home/pi/picframe_data/config/configuration.yaml:

    sensor_topic_head =  "homeassistant/sensor/" + self.__device_id
AttributeError: 'InterfaceMQTT' object has no attribute '_InterfaceMQTT__device_id'

Full config is attached.
configuration.txt

Am I missing something obvious? I cannot get anything to work.

Solved the issue by getting a new config file. There must have been some minor issue with it.
