* Full issue name: **Utility not found**
* Status: `ERROR`
* Related to: [Utilities](/docs/configuration/utils)
* Summary: A utility source element was not found
* How to fix: Make sure that the utility source element exists

Warhol was unable to create a style utility because the utility elements with
the selector defined in the configuration were not found. Check if the utility
element with the selector does exist in the pattern library.
