Error in dashboard

Hello,

We are currently experiencing issues with one of our dashboard. Attached is a screenshot of the error we get. The message we get is the following :
Error trapped: The element is unknown.
Try again in a few seconds.

Does anyone else ever had that error ? Does anyone have any insight on were we can start our troubleshooting ?

Thank you

Hi Samuel,
In order to further investigate, please could you let us know the data source used by this dashboard component? Are you using a filter? If so, please could you let us know which one?

Samuel Gagné [DevOps Member] commented 15th March 2023

Hello Miguel,
Yes that is an important thing I left off, thanks for asking. There is a query selecting info from power supplies (using a customed driver for this purpose). I added a screenshot of said query to my initial question. I also want to add that this dashboard worked perfectly for a while before inexplicably starting to have this error. No change whatsoever on the platform.

You can also troubleshoot by opening the network inspector and see which call throws an error.

Hello Kevin,
Thank you for the suggestion. I have to say it is the first time I hear of this network inspector. Is it a tool installed directly on the server ?

Gelber Mahecha [SLC] [DevOps Enabler] commented 15th March 2023

Hi Samuel. In the majority of browsers is a panel you can open by pressing F12. In that panel, there is a tab called network that will show you the messages between the browser and the server.

Hello Gelber
Yes of course, I did not think about that, thank you !

Hi Samuel,

This is an internal error which is being propagated and displayed on the dashboard. It's unrelated to your dashboard and query, instead I believe there's an inconsistency on the element level. I suggest to get in contact with our technical support so that we can help you further.

Technical:

Your query is getting data from all elements of a certain protocol. However, when fetching data for one of those elements, the error is thrown. So either the list of elements contains an element which is no longer available or a backend process (most likely SLElement) is not aware of the presence of a certain element.
