Angular 4 & lock v.11

Hi guys,
I added a
to my index page but when I running the angular app it shows me an error

dashboard:70 GET 403 ()

how can I fix it, Thanks

As you can see in its repository to install Lock, you should add <script src=""></script>

The 11.x just means you should replace x with the latest version, which you can always see in the repository linked above.
