In Google Apps Script, debug tool says e is undefined? Script doesn't work when editing in sheet

Question

The function in question:

function onEdit(e) {
  var range = e.range;
  var spreadSheet = e.source;
  var sheetName = spreadSheet.getActiveSheet().getName();
  var column = range.getColumn();
  var inputValue = e.value;
  var sheet = e.source.getActiveSheet(); if (sheet.getName() !== 'By Type' && sheet.getName() !== 'By State')  {return;}
  if(sheetName == 'By State' && column == 7)
  {  
     SpreadsheetApp.getActiveSpreadsheet().getSheetByName('By Type').getRange(range).setValue([inputValue]);    
  } 
  if(sheetName == 'By Type' && column == 7)
  {  
     SpreadsheetApp.getActiveSpreadsheet().getSheetByName('By State').getRange(range).setValue([inputValue]);    
  } 
}

isn't e already defined? What do I need to change?

Answer 1

I added the font change so that I could see the script doing something.

function onEdit(e) {
  //e.source.toast('Entry')
  const sh = e.range.getSheet();
  if(sh.getName() == 'Sheet0' && e.range.columnStart == 7) {  
    //e.source.toast('flag1');
     e.range.setValue(e.value).setFontWeight('bold');   
  } 
}
