Dynamically added assets prefix in the image URL - Ember-CLI

[mockey-jockey]

I am trying to load the app by using ember serve. Some of the images are not found error getting.
In CSS :

background-image: url(assets/images/image.svg);

its redirected to

http://localhost:4200/assets/assets/images/image.svg 404 (Not Found)

because in this URL two assets name added that's why the image is not found, I don't know where this asset added.

when adding '/' in the prefix of URL am able to see the image in the app.

background-image: url(/assets/images/image.svg);

its redirected to

http://localhost:4200/assets/images/image.svg - working fine

How to avoid two assets name without using '/' as a prefix for assets. Kindly help anyone pls...
