Script Editor Error: Not moving row based on specific value - google-apps-script

Question

I am trying to move a row of data from one sheet to another, when a specific value is recorded in a specific column.
I have found and adapted the following code to use in the Apps Script:
function onEdit(event) {
// assumes source data in sheet named Responses
// target sheet of move to named Completed
// test column with yes/no is col Y or 25
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = event.source.getActiveSheet();
var r = event.source.getActiveRange();
if(s.getName() == "Responses" && r.getColumn() == 25 && r.getValue() == "yes") {
var row = r.getRow();
var numColumns = s.getLastColumn();
var targetSheet = ss.getSheetByName("Completed");
var target = targetSheet.getRange(targetSheet.getLastRow() + 1, 1);
s.getRange(row, 1, 1, numColumns).moveTo(target);
s.deleteRow(row);
}
}
I have tested this on a copy of this data and it has worked fine. However, when using the original, nothing happens, when yes is entered in column Y. I have listed below some reasons why I think this may be occurring:
This is a shared sheet, I am not the owner. The owner has granted permissions
The responses sheet is connected with a Google Form
P.S. The following error appears when the script is executed from the editor, I don't believe this is an issue based on the type of trigger, it also appeared on my test and had no impact
TypeError: Cannot read property 'source' of undefined
onEdit # Code.gs:6
I would appreciate any suggestions on workarounds!

In order to help you to debug your script, just after function onEdit(event) { add a the following line:
console.log(JSON.stringify(event,null,' '));
The above will print the event object "printable" properties on the execution logs. This will allow you to validate, first, that the function is actually triggered when the spreadsheet is edited by using the Google Sheets UI, second, the coordinates of the edited cell as well the value entered into edited cell.
The coordinates will be shown as properties rowStart, columnStart, rowEnd, columnEnd.
Also you might find helpful to add the following line before the if statement.
console.log(s.getName());
NOTE: The error "Cannot read property 'source' of undefined" occurs when the onEdit function is run from the script editor as the event object is undefined.
