Star Craft II Editor Problem: Header File Not Available for Document Dependency

Dear Ladies and Gentlemen,

I wanted to publish a mod in your editor that contains properties from the campaign.

I wanted to create a mod for the players that automates the mining of vespene gas, but which has to be researched first.

When I wanted to publish this mod, I get the message:
„Header File Not Available for Document Dependency: Void Story (Campaign)“

So my question is: how could I fix this problem.
