Glimmer "transaction is null"


I’m trying to upgrade an app that was running version 2.5 to Ember 3. I got what I thought was everything cleaned up so that I could finally build the package okay.

The problem is, I am now getting a transaction is null error in my console.

To be honest, I have no clue were to even go to look for this.

Sorry for such a vague question, but I am simply not even sure where to start.


I narrowed it down to an old polyfill that we don’t need. So I just removed it.

import Ember from 'ember';

export function initialize() {
    placeHolderFunction : function(){

export default {
  name: 'placeholder-polyfill',
  initialize: initialize
