Getting multiple errors on build: error TS2610: 'override' is defined as an accessor in class 'Messages',....

[Stormi]

I am getting the same error on a dozen or so modules

Error: node_modules/@progress/kendo-angular-layout/dist/es2015/stepper/localization/custom-messages.component.d.ts:15:24 - 
error TS2610: 'override' is defined as an accessor in class 'StepperMessages', but is overridden here in 
'StepperCustomMessagesComponent' as an instance property.

15     protected readonly override: boolean;

Every component that has a Messages class of some sort throws it.

Have removed package-lock.json and cleaned the npm cache multiple times.

Hi Stormi,

Thank you for the provided details.

As you are using Angular 12, please update all Kendo package versions to their latest:

https://www.telerik.com/kendo-angular-ui/components/installation/up-to-date/#toc-updating-to-latest-versions

Then remove the node_modules folder and reinstall the dependencies. I hope that helps. Please let me know in case the issue persists.

Regards,
Svet
