I opened a support ticket and they did their investigation and reached back saying this is the error that they see:
InvalidFormatException: Cannot deserialize value of type java.math.BigDecimal from String "SOME_STRING": not a valid representation at [Source: UNKNOWN; line: -1, column: -1]
Can’t figure out what went wrong? It shouldn’t have given any errors since it was just me making a connection and importing the data, that’s it.
