Rest command with wled

Configuration
1

I have defined 2 rest commands to send text to my wled.

rest_command:
    wled_text1:
        url: http://192.168.111.215/json/state
        method: POST
        payload: '{"seg":[{"n": "{{text}}","id":0}]}'
    wled_text2:
        url: http://192.168.111.215/json/state
        method: POST
        payload: '{"seg":[{"n": "{{text}}","id":1}]}'

When I’m trying to use them everything is working…

action: rest_command.wled_text1
data: { 
  text: Welcome to the MATRIX!!!
}

But when I’m trying to send some data from oter devices (weather forecast data for example) it’s not working:

action: rest_command.wled_text1
data: { 
  text: {{ state_attr('weather.forecast_dom','temperature') }}
}

HA says that there is some syntax error…
Can anyone help me with that problem?

That is neither JSON nor YAML.
Where are you executing this?

action: rest_command.wled_text1
data:
 text: |-
  {{state_attr('weather.forecast_dom','temperature')}}

worked…
can You explain me why using |- after text helped?

Because templates need to be between quotes, always, and | (or >) does the equivalent.
