Question

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);
    });
