We upgraded to version 1.5 from 1.4. We have a child theme with its own pattern/component definitions. These were working fine in version 1.4. Now in version 1.5 we're getting the following errors in our testing suite:
Twig\Error\LoaderError: Template "@my_subtheme/news-list/news-item-list.html.twig" is not defined in "modules/contrib/ui_patterns/templates/patterns-use-wrapper.html.twig" at line 9. in Twig\Loader\ChainLoader->getCacheKey() (line 98 of /vendor/twig/twig/src/Loader/ChainLoader.php).
I've reviewed #3335833 and while it seems related, the patch there didn't resolve this issue.
1. Add a new component/pattern to a child theme
2. Be on version 1.5 of `ui_patterns`
3. See TWIG error
Active
1.5

I am sorry we didn't address your issue, but so much happened in one year and I hope you are not meeting this anymore.
For closure: We were able to resolve this internally and don't believe it was a problem with the module. It had to do with the a child theme pattern.
