Error ''Identifier 'territoryFromName' has already been declared" on AOT build with Angular & Kendo UI

Very recently, and without any version change to our package, our AOT build failed with this error message :

ERROR in chunk vendor [initial] [name].bundle.js Identifier

'territoryFromName' has already been declared (13:9)
}

}

function territoryFromName(name, identity) {
var likelySubtags = __WEBPACK_MODULE_REFERENCE__7_636c6472__.supplemental.likelySubtags;
var parts = name.split("-");

function territoryFromName(name, identity) {
var likelySubtags = __WEBPACK_MODULE_REFERENCE__7_636c6472__.supplemental.likelySubtags;
var parts = name.split("-");

We always refresh the node_modules folder (nuke + npm install) before any build, and the error showed up very recently (around last Monday 2018-08-29).

We haven't done any changes in the package versions since the last builds.

The build without AOT still works fine without any error.

How to fix this error ?

I also ran into this error. I did not explicitly have @telerik/kendo-intl installed in my package.json. It was being installed as a dependency for @progress/kendo-angular-intl at version @1.4.1.

I npm installed @telerik/kendo-intl to the latest version @1.4.2 and this resolved my error. @Nour - If you look at the difference between @1.4.1 and @1.4.2 you will noticed that the Kendo team removed the duplicate declaration.

ng add

npm install

@progress/kendo-angular-intl

@telerik/kendo-intl

I have been digging to find what's wrong with my application since I haven't done any recent updates, and yet still facing this error !

Inside the file:
node_modules@telerikkendo-intldistescldrterritory.js

node_modules@telerikkendo-intldistescldrterritory.js

there is a duplicate declaration of the function territoryFromName one with just name as a parameter and the other one has two parameters name & identity

territoryFromName

name

name

identity

The first one has no use and I just removed it from the file and saved it and it worked just fine.

PS. I believe they would fix this bug very soon, but for now this worked for me.

@kendo-angular-intl

@telerik-intl

Just delete this line from the package.json file :

package.json

"@telerik/kendo-intl": "1.3.2",


After some research, we found that territoryFromName was defined in the kendo-intl related modules.

territoryFromName

There seems to be some dependency confusion in the kendo packages, and it looks like the @telerik package was only redefining dependencies from the @progress kendo-angular more recent packages.

From what I understand, this has come in conflict with our @progress/kendo-angular-intl package

@progress/kendo-angular-intl
