Given the following code:
$storage = $this->entityTypeManager->getStorage('group_type');
$group_type_ids = $storage->getQuery()
->notExists('third_party_settings.subgroup')
->execute();
and there being a group type that does not have any third party settings, I'd expect to get said group type's ID from the query.
Instead, I receive nothing. This is because of the following lines in Condition::matchArray()
if (is_array($data[$key])) {
$new_parents = $parents;
$new_parents[] = $key;
if ($this->matchArray($condition, $data[$key], $needs_matching, $new_parents)) {
return TRUE;
}
}
// Failing the above block leads to FALSE return value.
So unless the full parent path to the property (in this case third_party_settings) is set, matchArray() will never get to call match() where it checks the IS NULL condition.
