Alteryx Server Usage Report
Cause
The error happens when there are no collections on the gallery/server as the MongoDB input tool would not have any data to read from the "collections" collection.
Resolution
1. Navigate to Alteryx Gallery -> Collections > Add New Collection
2. Add a workflow or schedule job to this new collection
3. Re-running the Alteryx Server Usage report would give the expected results once you have at least one collection ion your server/gallery.
