Hi Telerik Team,
when using the simple example below, there few warnings/errors apear in console
can you check if this is an issue with Typescript definition or some bug ?
];
<Breadcrumb data={items}/>
Warning: Failed prop type: KendoReactBreadcrumb: prop type `breadcrumbOrderedList` is invalid; it must be a function, usually from the `prop-types` package, but received `undefined`.This often happens because of typos such as `PropTypes.function` instead of `PropTypes.func`.

Hello,
Thank you for the code.
I inspected it and noticed that all of these are propTypes warnings, not TypeScript errors, and should not affect building the application.
Still, I made different tests locally, and none of these errors occurs on my end. Is it possible to share an example reproducing the errors and I will be happy to take a look at it
Regards,
Stefan

Hi Stefan,
Thanks for the quick response !
looking into this propTypes warnings,
I dont have 'prop-types' installed in my package.json
https://www.npmjs.com/package/prop-types
should i install it ?
is it a dependency of the KendoReact library ?
if so, is it mention in the documentation that it should be installed as dependency ?
Thanks,
Hello,
This package is used internally and it is installed automatically when installing our packages.
Please advise which is the user version of the component that is used, as this could have been fixed in the latest one?

Thanks Stefan !
Indeed, it solves the issue:
$ npm add --save prop-types
$ npm add --save-dev @types/prop-types
