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

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...

Reproduce the asset lookup with `ember serve` using a CSS URL such as `assets/images/image.svg`, then trace where the second `assets` prefix is introduced. Done means the unprefixed CSS URL resolves to `/assets/images/image.svg` without requiring a leading slash; no source file or test is named in the issue.
