Problem/Motivation

While using Patterns in views, getting error for the selected component/pattern

Twig\Error\LoaderError: Template "@organisms/card-carousel/_icon-card-carousel.twig" is not defined in "modules/contrib/ui_patterns/templates/patterns-use-wrapper.html.twig" at line 9. in Twig\Loader\ChainLoader->getCacheKey() (line 9 of /var/www/html/docroot/modules/contrib/ui_patterns/templates/patterns-use-wrapper.html.twig).

The name of the template in the error will change according to the chosen pattern/component in the Pattern.

Steps to reproduce

1. Create a view
2. Choose Format and Style as Pattern
3. Choose Pattern in the settings
4. Check the console and error logs

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes

Thanks a lot Prashant. Can you do a MR instead of a patch?

I am not familiar with the use wrapper system in UI Patterns 1.x. Are you sure the fix needs to be in the Twig template? There is nothing we can do earlier, at PHP level?

I suggest we have to show this warning message
Pattern Views row plugin does not support preview.
instead of error
