using puppeteer-recorder to record video of browser

Add two empty functions called prepare and render in the options.

await record({
  browser: global_browser, // Optional: a puppeteer Browser instance,
  page, // Optional: a puppeteer Page instance,
  output: path + 'output.webm',
  fps: 60,
  frames: 60 * 5, // 5 seconds at 60 fps,
  prepare: function () {}, // <-- add this line
  render: function () {} // <-- add this line
});

Basically it's missing some default functions and the error is not handled properly.

I know this would be a very late response to your question, but nevertheless.

A years ago, I visited this same stack-overflow thread and I had similar challenge of finding a screen recorder library which does a good job a capturing the video as well as offers an options to manually start and stop the recording.

Finally I wrote one for myself and distributed as NPM library...!!

Hope this is helpful...!!
