I did some digging to the code and seems like on line 121 of info.js the const getHTML5player returns null due to html5playerRes being null.
I can do some further debugging if thats needed.

Looks like this regex change solved the entire problem for me:

const getHTML5player = body => {
  let html5playerRes = /"jsUrl":"([^"]+)"/.exec(body);
  return html5playerRes ? html5playerRes[1] : null;
};

The original regex which searches for a script tag is sometimes failing beacuse the response does not include the specific script tag.

I'm also getting this error all of a sudden. I don't used to get it

UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]: The "url" argument must be of type string. Received undefined

Looks like this regex change solved the entire problem for me:

thanks for this

I'll have to try that regex change. If it works like a charm might do a pr to fix it.
