I'm trying to upgrade from Drupal 8.5 to 8.6 and I keep getting this error:
[info] Undefined index: scheduled_transition_state BaseFieldOverride.php:167 TypeError: Argument 2 passed to Drupal\Core\Entity\ContentEntityStorageBase::onFieldDefinitionUpdate() must implement interface Drupal\Core\Field\FieldDefinitionInterface, null given, called in /var/www/bwd/docroot/core/lib/Drupal/Core/Field/Entity/BaseFieldOverride.php on line 207 in /var/www/bwd/docroot/core/lib/Drupal/Core/Entity/ContentEntityStorageBase.php on line 441 #0 /var/www/bwd/docroot/core/lib/Drupal/Core/Field/Entity/BaseFieldOverride.php(207): Drupal\Core\Entity\ContentEntityStorageBase->onFieldDefinitionUpdate(Object(Drupal\Core\Field\Entity\BaseFieldOverride), NULL)
I've got a custom profile and lots of configuration to import, but it all works fine on 8.5. I'm using
blt setup -n to install Drupal. I've got BLT and Lightning and I suspect one of them is causing the problem, but I can't remove them from my project.
