This is a fix for Nightmare JS to allow making screenshots when the website forces a JavaScript redirection

screenshot.js

var n = Nightmare({
  switches: { 'ignore-certificate-errors': true, 'force-device-scale-factor': options.scale ? options.scale.toString() : '1' },
  show: typeof options.show === 'boolean' ? options.show : true,
  width: options.width || 1280,
  height: options.height || 720
});


n
.viewport(options.width || 1280, options.height || 720)
.goto(url)
.wait(options.waitAfterSelector || "html")
.wait(options.waitMilliseconds || 1000)
.screenshot(
  path || undefined,
  options.clip || undefined
)
.then(function (buff) {
  callback(null, buff);
})
.catch(function (err) {
  return n
  .screenshot(path || undefined, options.clip || undefined)
  .then(function (buff) {
    callback(null, buff);
  })
  .catch(function(){ callback(err) });
})
.finally(function() {
  return n.end();
});
