Error deploying QuickAction using Ant – creating child campaign record

Hi there,

I am trying to use Ant to deploy metadata and I'm running across an error that I cannot for life of me resolve. I get this error when trying to deploy a QuickAction:

Error: Target object does not have a valid lookup or master-detail reference to the parent object

The QuickAction just creates a child Campaign object. I get the exact same metadata set up when I create a QuickAction in the UI and then pull down the metadata. The relevant portion of the metadata looks thusly:

<targetObject>Campaign</targetObject>
<targetParentField>Parent</targetParentField>
<type>Create</type>

Clearly Campaign has a lookup to itself. I've double-checked permissions to make sure my user has access to it, which it does. I can't think of anything else to look for and the Internet has been no help, so far. I'd appreciate any guidance.

Thank you!
