I see this error when I press F12 in chrome, but strangely things still work. There seems to be no problems.
The controller with the name \'AccountUpdateVie
i import the file, in index.html and my problem solved,
<script src=".../AccountUpdateStep1ViewModel.js"></script>
You had 'AccountUpdateViewModel controller. but you didn't registered it in your route.config. if you didn't config means you never use it anywhere.
please remove unwanted model. or register it in the rout config section.
