Unhandled JS Excaption: Invalid Character '@' no stack

I have used decorator on React Native with typescript. I can use decorator everywhere but I can’t use as parameter decorator. For example

@Client('API_LINK')
export class Service {

   @Request<any>('/profile/:id', MethodEnums.GET)
   getDeneme(@UrlParam('id') id: number): any {
       return null
   }

}

Client and Request work but UrlParam give an error as Unhandled JS Excaption: Invalid Character ‘@’ no stack

So what can I do?
