Why do I get this error when I'm trying to create models from database?

I'm trying to create models from my Oracle database 10g using Entity Framework Core 5 dbcontext scaffold:

dotnet ef dbcontext scaffold "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=mssrv.infofer.local)(PORT=1533)))(CONNECT_DATA=(SERVICE_NAME=medusa)));User ID=TRAFICALERT_EFC;Password=traficalert" Oracle.EntityFrameworkCore -o Entities -f

However, I got the following error:

2021-05-05 08:21:12.783360 ThreadID:1   (ERROR)   OracleDatabaseModelFactory.Cre

Why do I get this error when I'm trying to create models from database?

Thank you.

The fine manual says minimum oracle 11.2 for that provider

Upgrade your db or change provider
