After a recent upgrade from 3.6.1 to 4.0.2 Designer has decided to not
work properly. After the upgrade was complete we created a new project
in Designer and imported all of the updated drivers and workflows from
the vault into our new project. During the import Designer threw an
error that it could not find the referenced packages for the User App
and Roles drivers. After that the workflows were imported but any
attempt to deploy any workflow it throws a validation error. When we run
project checker all workflows say "No version (null) found". We have
workflows that need to be updated but we are unable to deploy any
changes. Any help would be greatly appreciated.
