I am trying to execute a copy activity where I am trying bring inmultiple tables from Oracle database through an on-prem gateway.
However I am getting the below error :
Failure happened on 'destination' side.
'Type=System.InvalidOperationException,
Message=Cannot downgrade the minimum reader version,
Source=Microsoft.DataTransfer.ClientLibrary,'
Can anyone help me understand what this error means and what should I be looking for in my destination lakehouse to fix this error ?
I've found these errors to be very misleading at times.
For troubleshooting:
On the source side, does the 'Preview Data' load for you?
Is the destination set to overwrite or append?
If it is set to OverWrite, have a look in the code from the view menu and check that it doesn't say OverwriteSchema.
If it does, you can change it to Overwrite and see if it runs.
