TypeError: e is undefined

Since last update I have this error in my log:
Logger: frontend.js.latest.202302020
Source: components/system_log/init.py:256
First occurred: 10:45:28 (16 occurrences)
Last logged: 10:52:15
http://homeassistant.local:8123/frontend_latest/b1148040.js:1:5377 TypeError: e is undefined

It has something to do with state_history but i don’t know the solution. It’s visible in dwains dashboard when there is no hisory of a sensor I believe.

I’m the only one with this problem?
Using Dwains dashboard, would the problem be there?

@John_P I’m also seeing a similar error more and more recently, however I’m not using Dwain’s dashboard. An example of the error I see is:

I’ve had a look at the b1148040.js in a browser and js checker but don’t have enough experience or knowledge to troubleshoot this error any further. Have you made any progress?

No but I’m glad I’m not the only one.
I’m convinced it has something todo with entities without a record in history.
In past I got a message No state history found but that message is disapeared.
Hope some of the devs wilt shine a light on it soon.

Still no solution,

Some body?

Horay since last update the error finaly is gone
