Hello @johnreytanquinco how did you get that message exactly?

[johnreytanquinco]

I was trying to fix this issue , and able to access /pattens link by just doing this step. Then I received that warning message in Drupal logs.

I'm having a very similar issue, but a little different in that when my site attempts to build, when Drupal is looking up the dependency, such as my_custom_theme, the build error shows: drupal_get_path('module&', 'my_custom_theme')

Of course, my_custom_theme is not a module, it's a theme. This seems to stem from the fact that the feature module YML has a dependency on that theme, such as: custom_paragraphs.yml: `name: 'Paragraph Components' type: module description: 'Shared and reusable paragraph components.' package: Custom core: 8.x dependencies:

• field
• field_layout
• layout_discovery
• link
• media_entity
• node
• my_custom_theme
• paragraphs
• text`

Essentially, I configured the field mapping for UI Patterns on the paragraph fields, and because of that integration, I think that's why the dependency on the theme occurs.

I put together a patch for Features to resolve this issue:

• https://www.drupal.org/project/features/issues/2924625

Please give it a spin, it should help with this.

Thanks for following up @damienmckenna ! @joshuaboltzmc does this Features patch solve the issue for you?
