History bar graph lost after update


After updating to 2021.3 the bars in History are lost. The graphs are still there.

I can’t find anything explaining this in the changelog?! :thinking:

Have a nice weekend!


I am seeing this as well on 2021.3.2. If I search for a specific entity it will show the bar for it though, so the data is there.

It seems to have only started when I switched the recorder to use MariaDB yesterday. If I remove the recorder configuration and revert to sqlite the bars return.

I have the same problem after update to 2021.3.2

No history bar
and the error:
2021-03-07 21:04:32 ERROR (MainThread) [frontend.js.latest.202103025] http://home:8123/frontend_latest/chunk.ab01d5a9d4bd1e838d41.js:179:939 Uncaught TypeError: Cannot read property ‘attributes’ of undefined

Did you find any kind of solution or workaround ?


Hi Thorsten did you find a solution ?


No. If it’s still there in the next release I think it’s time for a bug report… :thinking:

Hi folks,

I’m having the same issue. Following. Let me know if any of you report the bug. I’ll throw in my details too.


I am also seeing this issue. It seems it only occurs when I use the “history:”-option in my configuration to exclude certain domains/entities/entity_globs so that they are not shown in the history. Can someone confirm that the issue disappears when removing the “history:”-section from the configuration?

Same error here, all versions are up to date, running Hass.io on a Pi4, has been perfect for months but now the history is not showing, its still there, i just can’t see it :frowning:

I submitted a bug report:

Please comment there!
