Your folder Id is not valid.

It ends with "?this=true". That can't be right.

https://drive.google.com/drive/u/0/folders/1ApXGgAL9G5X8Wy9HBrKSbmHviLLjT_L8?ths=true    -  this is the folder url ...what should i copy ?

[Paul Armstrong]

It is my observation that a Drive ID, whether it be for a folder or a file, is only ever an alphanumeric value. Your value ends with a query string which makes it even less valid. 

Drop the ?ths=true. Leaving '1ApXGgAL9G5X8Wy9HBrKSbmHviLLjT_L8'

I use this code to get an ID from a file or folder URL or a team drive.

getIdFromUrl(url) {

  var res;

  var m = url.match(/[-\w]{15,}/);

  if (m && m.length > 0) {

    res = m[0];

  }

  else if (url.length > 39) {

    // could be a teamdirve

   res = url.slice(39);

  }

return res;

}
