Mini-graph-card: [0.106.0b0] Uncaught TypeError: Cannot assign to read only property 'index' of object

[TheZoker]

Since the new beta 0.106.x I get this error in my frontend:

mini-graph-card-bundle.js:1 Uncaught TypeError: Cannot assign to read only property 'index' of object '#<Object>'
    at mini-graph-card-bundle.js:1
    at Array.forEach (<anonymous>)
    at HTMLElement.set hass [as hass] (mini-graph-card-bundle.js:1)
    at HTMLElement.value (hui-view.ts:61)
    at HTMLElement.value (hui-view.ts:337)
    at HTMLElement.<anonymous> (hui-view.ts:68)
    at r (fire_event.ts:76)
    at create-element-base.ts:72 

Also lovelace does not display anything anymore.
When I remove mini graph card js, the error is gone and lovelace loads normal again.

Noticed this too late after submitting my own duplicate 106.0b0 issue (now closed).

Thanks, will have a look at the changed this weekend.

Damn I was hoping I could merge the pr manually to get it working again.....

@DavidFW1960 Clone this repo, checkout the 0.106.x-compatibility branch and build from source as per developer instructions in the readme 😉

[DavidFW1960]

I'm sure that's simpler than it looks but above my pay grade I think

[DavidFW1960]

I'm clearly cleverer than I thought I am as I managed to build it and it seems to be working...

[DavidFW1960]

OK it works but it causes the whole GUI for any view with that card on it to slow down dramatically... to the point of being unusable

EDIT: It's not the card slowing it down... seems everything is slow right now..

@DavidFW1960 Do you use the history card?
Could be related to this error:

@TheZoker 100% correct.. it's the history card slowing everything down. I rolled back to 0.105.5 nd @kalkih custom-card I built as per above works fine in 0.105.5 and 0.106.x as well. Just waiting for b1 now.
