Rest sensor => extract a specific line / value

Configuration
1

Hey i have a rest sensor that executes a .js file
the output is more then 255 chars, i am only interested in this line:

minValue: { rawValue: 0, value: 0, valueType: 'RELATIVE' },

or even better, only the “value” => 0

this is my rest sensor, but it doesnt work, help is appreciated

  - platform: rest
    resource: http://192.168.0.17:8123/local/test.js
    name: Test
    scan_interval: 500
    value_template: '{{ value | regex_findall_index("minValue: { rawValue: 0, value:(\d+)", ignorecase=true) | int }}'

Is there also a way to actually see the 255 max character string in some log file? I want to see if the command was successful in first case
