Hi,

We are testing the next version of nativescript-vue and the webpack tag of NativeScript in preparation for 6.0.0. When changing running an app on ios tns run ios with the following setup the below exception is thrown after you make changes to the app and it is livesynced.

Setup:

1. Install webpack tag of NativeScript globally: npm i -g nativescript@webpack
   2.Install webpack tag of nativescript-dev-webpack : npm i nativescript-dev-webpack@webpack
2. Install next tag of nativescript-vue : npm i nativescript-vue@next
3. Run an the app on iOS: tns run ios
4. App is synced and started correctly
5. Make a change to the source of the app to trigger livesync
6. Changes are synced, app is restarted and when it start it crashes

mcsofamiorkov:demo-vue amiorkov$ tns run ios
