Invalid Column Name when copying database between instances - sql-server

Question

I am using the Copy Database feature in SSMS. The source instance is v 2012, the target instance is v 2019.
I am able to copy other databases in the source instance to the target instance. This particular database fails.
This message is from the Windows Event Viewer on the target machine. "InnerException-->Invalid column name 'Description'." does not make sense because there is
a column with that name in one of the tables in the source database. I can't tell what table it's complaining about from the message in the Windows Event Log.
There is one table in the source database with a column called Description:
Event Name: OnError
Message: An error occurred while transferring data. See the inner exception for details.
