When performing a pre-migration check or copying a Nintex Workflow containing a Nintex Live action, Sharegate displays the following error message:
The workflow 'My workflow' cannot be copied because it has a Nintex Live action and this service is unavailable at the destination.
Any error code ending with: -185
