Create a google spreadsheet in same folder as current file

Question

I have a google form script that I want to create a spreadsheet in the same folder as the form.

  var thisFileId = form.getId();
  var parentFolder = DriveApp.getFolderById(thisFileId)
  
  spreadsheet = SpreadsheetApp.create(spreadsheetName);
  var spreadsheetID = spreadsheet.getId();
  var spreasheetFile = DriveApp.getFileById(spreadsheetID);
  spreasheetFile.moveTo(parentFolder);

I get an error on the last line :

"Exception: Invalid argument: parent.mimeType"

Answer 1

I believe your goal as follows.

• You want to create new Spreadsheet to the same folder with form.getId() .

Modification points:

• In your script, about the variable name form of form.getId() , if form is the Google Form, form.getId() is the file ID of Google form. I think that this might be the reason of your issue.
• In order to put the new Spreadsheet to the same folder with form , it is required to retrieve the parent folder of form .

When above points are reflected to your script, it becomes as follows.

Modified script:

From:

var parentFolder = DriveApp.getFolderById(thisFileId)

To:

var parentFolder = DriveApp.getFileById(thisFileId).getParents().next();

Note:

• It seems that when ID except for the folder ID is used for DriveApp.getFolderById(id) , no error occurs.

Reference:

• getParents()
