Execution failed: TypeError: - Following replacement of DocsList with DriveApp

Question

I now understand that my broken script began as a result of the recent depreciation of DocsList. Following instruction I have now replaced all instances of this to DriveApp. However execution still fails, multiple file copies are being made in various folders and emails are not sending. I would really appreciate is someone could help me fix this as this is killing my novice brain!

Here is the execution transcript.

And here is the referenced error code

function copy_file(path, file,new_name) {
  var file_copy = file.makeCopy(new_name);
      file_copy.removeFromFolder(DriveApp.getRootFolder());
      file_copy.addToFolder(DriveApp.getFolder(path));
  return file_copy;
}


function create_doc_in_path(path, filename) {
  var doc = DocumentApp.create(filename);
  var file = DriveApp.getFileById(doc.getId());
  file.removeFromFolder(DriveApp.getRootFolder());
  file.addToFolder(DriveApp.getFolder(path));
  return doc;
}

Answer 1

Zig Mandel is correct, you need to map each functionality of older api with newer api.more info of DriveApp

here is code may work.

function copy_file(path,file,new_name) 
{
  var folder = DriveApp.getFolderById(path);
  var file_copy = file.makeCopy(new_name);
  var document = DriveApp.getFileById(file_copy.getId());
  folder.addFile(document);
  return file_copy;
}

function create_doc_in_path(path,filename) 
{
  var folder = DriveApp.getFolderById(path);
  var doc = DocumentApp.create(filename);
  var file = DriveApp.getFileById(doc.getId());
  folder.addFile(file);
  return doc;
}
