Does it happen if you delete a resource element manually ?
Sorry but I don't understand your question. What resource?
I've just import the package and run the workflow.
The workflow fails when trying to delete resource element programmatically.
To check if this is a specific 6.0.1 issue you can try to delete a resource element in the vCO client
Also it is possible this error happens with a particular DB type and not another.
In any case I would recommend opening an SR. There may be workarounds.
In the meantime you can comment the part deleting the resource element. Deleting these allows to not have to overwrite these when you do another import (newer version of the plug-in or another plug-in).
Is this an official plugin and I can send a support request?
Despite the error and the delay, it seems to work now. I don't know the reason, is a newly installed vRO without any plugin added.
It is not but deleting a resource element via the scripting is a supported vRO feature.
