Composing of images depends on creating *.mask.png. So i think this gm chain for compose original png with *.mask.png should be places inside of .writeAsync then(() => { when writeAsync is asynchronous.

.resize(maxSize * marginPercent, maxSize * marginPercent)
.gravity('Center')
.extent(maxSize, maxSize)
.write(path.normalize(destinationPath), function(err, value) {
if (!err) {
gm()
.compose('copyopacity')
.in(path.normalize(destinationPath))
.in(path.normalize(destinationPath + '.mask.png'))
.out('-composite')
.write(path.normalize(destinationPath), function(err) {
if (!err) {
console.log(`Wrote ${destinationPath}`);
// delete the mask
fs.unlink(path.normalize(destinationPath + '.mask.png'));
}
