Broken page: (Failed to execute 'removeChild' on 'Node')

Hello :wave:

I’ve catched this error in console. It appears when I translate the page with the browser built-in Google Translator.

Console error

Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.


I changed Discourse language to e.g. French and translate it with built-in Google Translator to English.

Without Google Translate no error appears but when I turn on Google translator, after the first topic page change on New & Unread Topics the page will completely froze (broke).

I show it with topic page change but this issue also appears other pages…e.g. on /about when changing between /faq, /tos etc. with navigation if Google Translate enabled.

Thank you :slightly_smiling_face:


This is a tricky one, is this a Google bug or Discourse one? Built in translators fiddle with HTML structure that then makes Ember get super confused and lose its grounding.

Yes, unfortunately it seems that this is the case. You are right, this is not a Discourse issue but rather a conflict between Ember and Google Translate. I have also found a report from 5 years ago in the Ember.js git repo regarding a similar issue. Thanks Sam :slightly_smiling_face:

I can ask our Ember friends if they have any ideas here, but all bets tend to be out if the DOM changes underneath it.
