Installable trigger created using “ScriptApp.newTrigger” has to be re-saved before it will run

问题

I have an Expenses sheet that I copy to the Google Drive folder for each of my relevant users. Each copy of the sheet needs an installable trigger that calls a function to insert additional rows when the last row of data gets edited. These are triggered using the onEdit event. The installable triggers work fine when created manually (via "Edit Current Project's triggers").

To simplify the process of setting up new users, I have scripted the creation of my trigger. Although the script creates the trigger and it appears exactly the same as the manually created one, it only works if I manually open up the trigger, re-select the function to trigger and re-save it.

I can confirm I am the owner when running the creation script.

The behaviour I'm seeing suggests to me that there is something incorrect with the function name in my script however it all looks fine to me. I'd really appreciate some help with this....

function createInsertRowsTrigger(){
  Logger.log('Id='+ss.getId());
createInstallableTrigger("onEditOfLastRow",ss.getId());
}

function createInstallableTrigger(funcName,ssId) {
      if(!isTrigger(funcName)) {
        ScriptApp.newTrigger(funcName).forSpreadsheet(ssId).onEdit().create();
      }
    }

function isTrigger(funcName){
       Logger.log('In isTrigger');
   var r=false;
   if(funcName){
     Logger.log('Function found');
     var allTriggers=ScriptApp.getProjectTriggers();
     for(var i=0;i<allTriggers.length;i++){
       if(funcName==allTriggers[i].getHandlerFunction()){
         r=true;
         Logger.log('trigger already exists');
         break;
       }
     }
   }
   return r;
 }

The full code is here....
