How about checking it length?

const customImage = tmpl.customImage.length ? tmpl.customImage.map(c => c.url) : "https://yourl img here";

Solution 2:^[2]

use instead of that: const customImage = tmpl.customImage.length ? tmpl.customImage.map(c => c.url) : "https://yourl img here";

Solution 3:^[3]

give your image url link in that array make that variable and use res.render to render your file

Is tmpl.customImage already an array, then why assign an array to customImage ?

You can handle the empty array here:

tmpl.customImage.push({"url":"https://yourimghere"}); // add to the end
const customImage = tmpl.customImage.shift(); // take from the top
