106 b: system monitor invalid config

must be missing the obvious,

but what is wrong in:

sensor:
## https://home-assistant.io/components/sensor.systemmonitor/
  - platform: systemmonitor
    resources:
      - type: disk_use
        arg: /home
      - type: disk_use_percent
        arg: /home
      - type: disk_free
        arg: /home
      - type: network_in
        arg: eth0
      - type: network_out
        arg: eth0
      - type: packets_in
        arg: eth0
      - type: packets_out
        arg: eth0
      - type: load_1m
      - type: load_5m
      - type: load_15m
      - type: processor_use
      - type: memory_free
      - type: memory_use_percent
      - type: memory_use
      - type: swap_use_percent
      - type: swap_use
      - type: swap_free
      - type: last_boot
      - type: ipv4_address
        arg: eth0

when it says this https://rc.home-assistant.io/blog/2020/09/29/release-116/#breaking-changes for the changes?

I get this in the log:

Mandatory 'arg' is missing for sensor type 'swap_free'. for dictionary value @ data['resources'].

but in the docs, there’s no mandatory arg??

this is probably the bug…

  "swap_free": ["Swap free", DATA_MEBIBYTES, "mdi:harddisk", None, True],
