Kendo-angular: @progress/kendo-angular-charts 4.1.5 -> error on prod

[meriturva]

Updating all packages to latest version (still on angular 9.1.11) i found that package @progress/kendo-angular-charts 4.1.5 on prod throws error:

main.3f436b464a06d00d92da.js:1 Uncaught TypeError: Cannot read property 'dateFormats' of undefined

With version 4.1.4 there is no such problem.

Thanks for reporting, I've managed to reproduce the issue. It's an odd one because the code that throws the error hasn't been modified for quite a while.

[meriturva]

In fact, I have another project quite old that now even with version 4.1.4 throws error on prod.
Do you have a version number without that issue? Just to run tests on it

[tsvetomir]

Fixed in @progress/kendo-charts v1.14.2 and @progress/kendo-drawing v1.8.1.
That explains why changing the @progress/kendo-angular-charts version was not effective.

Running npm update should update these depdendencies.
If that fails, remove node_modules, package-lock.json and re-install.

I will give it a try as soon as possible

Hi, @tsvetomir thanks for the answer.

From Kendo angular chart documentation (https://www.telerik.com/kendo-angular-ui/components/charts/get-started/) I'm seeing @progress/kendo-drawing as a dependency but not @progress/kendo-charts.

Do the documentation needs to be updated?
I'm testing in our production mode this solution

[meriturva]

Ok it works... I forgot to update the lock file on CI.
Now seems ok.

@juanslingerURUIT The "kendo-charts" package is a direct dependency and is not listed together with the peers.

To make sure that everyone gets the update, we've released v4.1.6 of @progress/kendo-angular-charts that explicitly references the fixed version.

Sorry for the trouble!
