Question

I'm getting the

"We're Sorry, a server error occurred. Please wait a bit and try again."

when trying to save the script

If I run the script as is, it runs an older version

Here's my code:

function myFunction() {
  
  var ss2 = SpreadsheetApp.getActiveSpreadsheet();
  var sheet2 = ss2.getSheets()[0];

  var cell = sheet2.getRange("D3:D6");
  cell.setValue("Out");
  var cell = sheet2.getRange("D8:D12");
  cell.setValue("Out");
  var cell = sheet2.getRange("D14:D17");
  cell.setValue("Out");
  var cell = sheet2.getRange("D19:D31");
  cell.setValue("Out");
  var cell = sheet2.getRange("D33:D42");
  cell.setValue("Out");
  var cell = sheet2.getRange("D44:D50");
  cell.setValue("Out");
}

Answer 1

I got it figured out. I deleted the whole project and copy/pasted the same code into a new one (added the appropriate triggers) and I'm getting no errors now.
