I took a look at #103 and realized its pretty much taken care of with the merging of #99 as data frames are only added to
processed_dfs
if they are not empty.I only found a slight inconsistency in the error message. In case
processed_dfs
is empty it would only report: "The region aggregation for model {model} resulted in an empty dataset" which can be misleading in case of multiple models.I adjusted the error message and modified a unit test to test for that.
