[Deprecation] Listener added for a 'DOMNodeInserted' mutation event. Support for this event type has been removed.

[ESRI_User_121]

We are using ArcGIS Enterprise version 11.0. Since may we can't see our nav bar and login from Chrome as 'DOMNodeInserted' function has been deprecated. Now we can't even login to our own portal. We are getting this error on the console: esri-global-nav.js:1 [Deprecation] Listener added for a 'DOMNodeInserted' mutation event. Support for this event type has been removed, and this event will no longer be fired. See https://chromestatus.com/feature/5083947249172480 for more information. I have checked and found that ESRI has released patch for 11.2, 11.1, 10.9.1, and 10.8.1 but 11.0 is not available. How do we fix this issue?

You cannot fix this issue for 11.0 because Esri is no longer supporting 11.0. Esri will not be releasing a patch to fix this for 11.0. The only true "fix" is to upgrade to a higher version. Alternative "fix" is to use a non-Chrome browser like Firefox. 

See this for more information. https://support.esri.com/en-us/knowledge-base/impact-of-google-chrome-and-microsoft-edge-127-updates...

Is there any way to update/modify the JavaScript code manually to solve this issue? We spent a lot to buy the perpetual license and we can't really upgrade at the moment. Most of our users and engineers use chrome/edge as their default browser.

Unfortunately.....this is the risk of using deprecated software.

At the bottom of the page of the URL I posted, there is a workaround for Chrome/Edge that will only work until Chrome version 135 is released, which will last about nine months from when they deprecated this functionality back in July.

Alternatively, you might be able to download an old version of Chrome, then have your IT department disable Chrome from updating. But.....you're putting your organization at risk for using deprecated software (both Esri and Chrome). Keep in mind that by using deprecated software, you won't be getting new security patches that will protect your organization. So, you'll need to talk to your management and/or IT and decide what's best.

Hello @ESRI_User_121 ,

This is certainly a challenging situation. However, I understand that switching browsers across an organization or upgrading the environment to a newer version is not a decision that can be taken lightly. It is also unlikely to be an easy task to accomplish in a short period of time. As an alternative, you could consider leveraging the `MutationEventsEnabled` property as mentioned in the following article, which @RyanUthoff mentioned:

https://support.esri.com/en-us/knowledge-base/impact-of-google-chrome-and-microsoft-edge-127-updates... 

For more reference utilize the below:

For Testing:

• Edge: Microsoft Edge Browser Policy Documentation | Microsoft Learn
• In Edge, go to edge://flags, search for "mutation", and set Enable (deprecated) synchronous mutation events to Enabled.  

• Chrome: Chrome Enterprise Policy List & Management | Documentation
• In Chrome, go to chrome://flags, search for "mutation", and set Enable (deprecated) synchronous mutation events to Enabled.

If the above solution works, it seems that applying this setting through a group policy would be a simpler approach compared to switching browsers or upgrading the environment. This method would minimize disruption and not require any additional effort from end-users.

Furthermore, I can look into finding the steps to deploy this as a Group Policy and share them with you. However, I would strongly recommend reaching out to your IT team for assistance with this process. That said, if you still need further details or clarification, please feel free to let me know, and I will do my best to provide the necessary steps.

Hope it helps!
