I am facing another issue on this superbadge, specifically in Challenge #10, i am getting the following error:
The Campaign Influence Lightning report must have the correct 1. Aggregate, 2. Columns, 3. Groupings, and 4. Filter.

The requirements have no mention about what fields, groupings, filters, aggregates to include in the report. What am I missing?

The solution all over the web, http://titancronus.com/blog/2014/05/01/salesforce-acquiring-dependent-picklists-in-apex/ does not work in all cases it seems.

Is there an official solution yet, or maybe an alternative? That code above is the only one that seems to be floating around on different sites.
