ERROR Error: Uncaught (in promise): ProgressEvent: {"isTrusted":true}

i am making a put request from my ionic app to an api :

     updateDeviceToken(params):Promise<any>{
        return this.http
          .put(this.endpoint + '/devicetoken',params)
          .toPromise()
          .then((response: any) => response);
      }

i am getting this error :

ERROR Error: Uncaught (in promise): ProgressEvent: {"isTrusted":true}

when i run the app on the web i don't get any error and the PUT request is done correctly i get this error whenever i run on the emulator or real device
