TypeError in WorkflowConfigTransition::setWorkflow when importing config

Using Drupal 8.5.1 and latest dev version of Workflow. Successfully set up a workflow with access and tranasitions via the UI. Successfully added Workflow fields to Content Types. Successfully transitioned Content with Workflow fields in Content Type.

Issue: Exported Configuration via the UI. When attempting import using:

drush cim --partial --no-halt-on-error --source=../config/sync -y

I get the following error:

Argument 1 passed to Drupal\workflow\Entity\WorkflowConfigTransition::setWorkflow() must be an instance of Drupal\workflow\Entity\Workflow, null given, called in [error]
