I'm using the node 14 version am facing a conversion error in the spawn child process. enter image description here
var args = [
'/tmp/1633000412878/firstFrame.png',
'/tmp/1633000412878/lastFrame.png',
'(',
'./masks/fade.png',
'-evaluate',
'add',
'0%',
')',
'-composite',
'-size',
'1024x576',
`enter code here`'rgba:-'
];
var ls = spawn('convert',args);
ls.stderr.on('data', function (data) {
console.log('stderr: ' + data);
});
