It's one of the generic messages here is what is interesting It loaded most of the tables except for the last few, and it works in DataMaker, so I think there is a parsing error in Portal. Again I tested in 4.9.248 and 4.9.81, and I see the same result. Below shows that last 3 table didn't get loaded using Portal and then below is the DataMaker loaded generator.
Using Datamaker it loaded all the tables
