Warning: Undefined array key "node_title"

[Heb-l]

After upgrading our Drupal 9 (9.3.19) site to PHP 8.1 we're seeing warnings like the below appear on various pages. They seem to appear after a Drupal cache clear and then stop showing until the next Drupal cache clear.

Warning: Undefined array key "field_date" in Drupal\ui_patterns_field_group\Plugin\field_group\FieldGroupFormatter\PatternFormatter->preRender() (line 105 of modules/contrib/ui_patterns/modules/ui_patterns_field_group/src/Plugin/field_group/FieldGroupFormatter/PatternFormatter.php).

Warning: Undefined array key "node_title" in Drupal\ui_patterns_field_group\Plugin\field_group\FieldGroupFormatter\PatternFormatter->preRender() (line 105 of modules/contrib/ui_patterns/modules/ui_patterns_field_group/src/Plugin/field_group/FieldGroupFormatter/PatternFormatter.php).

Do you have any guidance please?
