Making use of HACS clientraw integrations - configuration error

Hi all,
I wanted to make use of a integration HACS uses called clientraw.

There is an entry i need to make in my configuration.yaml i need to make.
However, everytime i make this entry, before i save it, the editer (i use is telling me there is an error at that point of the file.

sensor:
  - platform: clientraw
    url: "http://192.168.1.142/weather/clientraw.txt"
    monitored_conditions:
      - temp
      - humidity

What is the problem?
I’m wary about saving the inputted text into the configuration in case homeassistant is unusable afterwards.
