Can't get it to work. Error from python?

[luvxinh]

• [Y] I have read the README.md file and visited the Documentation to see if the information there helps.
• Also have gone through the closed issues, but I don't have same errors.

Describe the bug After installing python, I create the yaml file.

pi@pi21:~ $ sudo nano test-config.yml

with the following content

mqtt:
  host: core-mosquitto
  port: 1883
  user: "mqtt"
  password: "password"
  topic_prefix: /home/temp

# GPIO
gpio_modules:
  # Use the Raspberry Pi built-in GPIO
  - name: rpi
    module: raspberrypi

digital_inputs:
  # Pin 0 is an input connected to a doorbell button
  - name: Chun
    module: rpi
    pin: 4

sensor_modules:
  - name: dht22
    module: dht22
    type: DHT22 # can be  DHT11, DHT22 or AM2302
    pin: 4

sensor_inputs:
  - name: temperatureChun
    module: dht22
    interval: 5 #interval in seconds, that a value is read from the senso>
    digits: 4 # number of digits to be round
    type: temperature # Can be temperature or humidity

  - name: humidityChun
    module: dht22
    interval: 5 #interval in seconds, that a value is read from the senso>
    digits: 4 # number of digits to be round
    type: humidity # Can be temperature or humidity```

It's basically just to get the data off the DHT22 sensor.

However, when I run

`
pi@pi21:~ $ python3 -m mqtt_io test-config.yml
`

the following errors appear:

I just want it to run and publish something. I'm listening on homeassistant but there's just nothing

Are you able to use mosquitto_sub and mosquitto_pub test clients using the information you provided for the MQTT server in your configuration?
