Is there a way to sort through nested objects with unspecified keys?

I'm looking to extract specific information from a nested object with unknown keys and create a new array with it.

This data is retrieved from the CUPS API, where printer names act as keys. I want to filter based on conditions like 'printer-state' === 3.

const data = {
    'Expedition': {
        'printer-is-shared': false,
        'printer-state': 4,
        'printer-state-message': '',
        'printer-state-reasons': ['none'],
    },
    'Serverroom': {
        'printer-is-shared': false,
        'printer-state': 3,
        'printer-state-message': '',
        'printer-state-reasons': ['none'],
    }
}

Thank you!

I attempted using Array.filter() but couldn't quite get it to work as intended.

        'monitor-state': 1,
        'monitor-state-message': 'Normal',
        'monitor-state-reasons': ['none'],
    },
    'Kitchen': {
        'microwave-is-shared': false,
        'microwave-state': 2,
        'microwave-state-message': '',
        'microwave-state-reasons': ['overheating'],
    }
}
const filterObjectByPropertyValue = (obj, key, value) => {
      return Object.keys(obj)
        .filter(k => obj[k][key] === value)
        .reduce((res, k) => ((res[k] = obj[k]), res), {});
};

console.log(filterObjectByPropertyValue(details,'monitor-state',1))
