There is a way to set the pdf size in the following script?

Question

How do I set the pdf size as A4 in the following script? Also, is it possible to fit the sheet into a single pdf page?

function sendSheet() {
  var message = {
    to: "EMAIL",
    subject: "SUBJECT",
    body: "BODY",
    attachments: [SpreadsheetApp.openByUrl("URL").getAs(MimeType.PDF).setName("NAME.pdf")]
  }
  MailApp.sendEmail(message);

You can resize the PDF in the sheets url parameters like this.

Script:

function sendSheet() {
  EMAIL = '<EMAIL>'
  URL = 'https://docs.google.com/spreadsheets/d/<SPREADSHEET_ID>'
      + '/export?'
      + 'format=pdf'
      + '&size=A4' // size, (letter, legal, A4)
      + '&gid=0'; // sheetID

  // dummy call to get document access
  SpreadsheetApp.getActive();

  var response = UrlFetchApp.fetch(URL, {
    headers: {
      'Authorization': 'Bearer ' + ScriptApp.getOAuthToken()
    }
  });

  var message = {
    to: EMAIL,
    subject: "SUBJECT",
    body: "BODY",
    attachments: [response.getBlob().setName('NAME.pdf')]
  }

  MailApp.sendEmail(message);
}

There seems to be an option where you can "fit" your data into just a single page, but it will scale down your data instead (including the width).

The page size retains, but it will scale down the data into 1 page if exceeds a single page. See sample pdf with expected 48 pages:

scale=1 parameter:

scale=3 (fit to height) or scale=4 (fit to page) parameter:

As you can see, it is unreadable when dealing with large number of pages and trying to fit into 1.

I assume what you want is a single long page in your PDF containing your data in a continuous matter which is technically impossible since you can't modify its page height (only the size in totality)

UPDATE:

I found this comprehensive list of parameters here, feel free to test them and see if you might need something from the list below.
