is_loading error with dash3.0rc1 candidate

[benweinberg89]

I have a grid that works perfectly fine with dash 2.18.2 (and dash ag grid 31.3.0). When updating to dash3.0rc1, I'm getting ais_loading type error. The grid quickly shows up and disappears yielding this error. I can update this issue later with a reproducible grid, but I want to file before I forget. Here is the full error:

TypeError: Cannot read properties of undefined (reading 'is_loading')

Hi @benweinberg89

This is a known issue and there is a PR to fix it: #353

Any dash-ag-grid versions <=31.3.0 will need to be pinned to dash < 3.0

[gvwilson]

@benweinberg89 we are going to publish a release candidate for dash-ag-grid that includes #353 - I hope that'll be on PyPI today, and I'd be grateful if you could check your problem against it when it's available. thanks - @gvwilson

[gvwilson]

@benweinberg89 there is a release candidate for dash-ag-grid on PyPI if you would like to try that. cheers - @gvwilson

Hello! I did try the release candidate and it did fix the the is_loading issue, but then a undefined reading 'type' issue popped up.

Hi @koalaTcoder
Looks like you are using dash-mantine-components. Please try the prerelease

dash-mantine-components==1.0.0rc1

[koalaTcoder]

that fixed it.... yall are awesome !

[AnnMarieW]

One more point - when upgrading from dmc 0.14.6 be aware that the DatePicker was renamed to DatePickerInput (This happened in 0.15.0)

[koalaTcoder]

i didnt even realize i was on 0.14.6 at home, i actually had an issue on 0.15.3 at work which got me searching, thank you for the quick spot!

[gvwilson]

thanks everyone - can I now close this issue?

[AnnMarieW]

Yes - thanks 🙂
