ADF Xero Connector fails with dates prior to 1970

We want to integrate ADF with Xero. When we copy data from the Journals table we receive this error

Failure happened on 'Source' side. ErrorCode=UserErrorOdbcOperationFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=ERROR [HY000] [Microsoft][Support] (50090) Conversion from string to number failed with value '',Source=Microsoft.DataTransfer.ClientLibrary.Odbc.OdbcConnector,''Type=System.Data.Odbc.OdbcException,Message=ERROR [HY000] [Microsoft][Support] (50090) Conversion from string to number failed with value '',Source=XeroODBC_sb64.dll,'

After a lot of digging around we found the problem being a journal that has a date of <JournalDate>1920-08-01T00:00:00</JournalDate>, which in JSON comes back as "JournalDate": "/Date(-1559520000000+0000)/". And its this record where the copy activity fails.

I cannot change this record in Xero (an update just adds a correcting journal, but doesnt update this one), and I cannot copy the data because of this.

Is there anything I can do? Like can I tell the connector to use XML format? That seems to use a sensible notation...
