$parent of type Cake\Datasource\EntityInterface|array is incompatible with the type Saito\Posting\Basic\BasicPostingInterface expected by parameter $parent of App\Controller\Component\PostingComponent::prepareChildPosting().

            $posting = $newEntry->toPosting()->withCurrentUser($this->CurrentUser);

The method toPosting() does not exist on Cake\Datasource\EntityInterface. It seems like you code against a sub-type of Cake\Datasource\EntityInterface such as App\Model\Entity\Entry.

            $this->set(compact('posting'));
        } else {
            $this->set(compact('errors'));
            $this->viewBuilder()->setTemplate('/Error/json/entityValidation');
        }
    }
