Hello, I just started up a graylog server and its been going pretty good so far. I’ve been seeing some errors when loading some widgets that display the following: While rendering this widget, the following error occurred: NotFoundError: Failed to execute ‘insertBefore’ on ‘Node’: The node before which the new node is to be inserted is not a child of this node.

Any idea what this is? The error goes away if I refresh the page or run the query again.

TIA

Hey @_lluis,

it is always helpful to share your Graylog Version so we can know if you run into a known or new problem.

Where is the error displayed? In the widget? In the web dev console?

Could you please add the output from the web dev console? (F12 in the Browser)?

Hey \_lluis, thanks for reporting this!

Can you narrow down the error to a specific widget or a specific action you are doing?

Is there a list of steps we can take to reproduce it?

The one place I am able to replicate it at this point is with the “AD User Object Summary” dashboard from [https://marketplace.graylog.org/addons/da1d0f41-7e26-40ad-9a53-518692ed71e9](https://marketplace.graylog.org/addons/da1d0f41-7e26-40ad-9a53-518692ed71e9)  
If I edit any widget such as the “Created Accounts” then it will error a different widget in the page and I can edit the one thats got the error and the initial one that was edited works. If I just refresh the entire page they all load up.  
When I initially was seeing the issue if I was on the initial search tab and I was to aggregate any of the fields in the messages it would break the “All Messages” but that does not seem to be happening now. Recent changes I’ve done are change the logins over to LDAP and add in Apache for proxying the web traffic.

Its starting to happen more often now when I run a search with a larger time frame. Anything else you might need to try and diagnose this?
