Files with No Data - courseResources.csv

Files with No Data - courseResources.csv

According to:

"Files that contain no data rows are NOT permitted"

We have resources that we wish to share. We wish to assign those resources by classes, and not by courses. Initially I interpreted this as meaning that the courseResources file should have only the headers and no data rows, but that is contradicted by the above. Can anyone help me identify either what the correct setup should be, or if I am missing something about the way we are trying to assign resources?
