Return result function

hey. how to return the result?
If inside the block, there will be an error
I can't do it.
return a value outside the function

const parser = async (req, res) => {
    try {
        const { service, url } = req.query;
        if (service, url === undefined) return res.status(400).json({ undefined: 'check_fields' })
        if (regservice == 'de') {
            let ad = await axios.get(url),
            $ = cheerio.load(ad.data);
            let listItemsph = $(".card-slider ul li");
            listItemsph.each(function(idx, li) {
            const info = {
                title: $("#item-detail-title").text().trim(),
                price: $(".card-product-detail-price").text().trim(),
                photo: {
                   ph: $(li).find('img').attr('src')
                }
                };         
                // return info
            })
                               res.status(200).json(info)
        }
        
    }catch (err) {
        console.log(err);
        res.send("err")
    }
}
