Undefined array key(s) in Drupal\ui_patterns\Plugin\Derivative\EntityFieldSourceDeriverBase

Hello,
thank you for reporting you error.
Would you share with us, the list of enabled contrib and core modules please?
from the trace, i may guess "entity_embed"?
many thanks in advance

@yasmeensalah, Could you mention the drupal version on which you are getting the following issues?

Hi,
answering @just_like_good_vibes:
Yes i have entity_embed, and most probably it's causing both errors

@nidhish
I have Drupal 10.4.1. , after updating ui-patterns to 2.0.0-rc2 most of the issues have been resolved (all issues listed here https://www.drupal.org/project/ui_patterns/issues/3498456 🐛 PHP warnings with Metatag module Active )

Only 2 things are left (filed storage line 416) and (entity_embed_fake_entity line 322)

Hello @yasmeensalah,
thanks, i will try to reproduce and post the correction

Yes, the changes correct the problem I have on 2.0.0-rc2
Great, thanks!
