How to execute a VBO using Drush
From the looks of the error, it looks like vbo operation or the action is trying to insert a blank value into the field_data_field_workflow_states table. 

Without actually seeing any code it's a little harder to determine what's going on in the vbo or the action, but check either list_of_node_for_expire or action::workflow_vbo_given_state_action and make sure you're working with the correct data before it makes the database request.
