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
The generator log shows that the file is corrupt containing non UTF characters
com.fasterxml.jackson.core.JsonParseException: Invalid UTF-8 start byte 0xad
It is the first entry for the record I_DIST_ODPD_RECORD without data imported
The dash character seems to be invalid.
Release : 4.9
Component : CA Test Data Manager
Need to clean up the file and remove bad character.
