I'm testing out the new arcpy.management.CreateDatabaseConnectionString() with a connection to a 10.8.1 enterprise geodatabase in Oracle, but I can't seem to get any workspace properties from Describe. Everything results in OSError: "CIMDATA=<CIMStandardDataConnection xsi:type=...rest of connection string" does not exist
If I create the connection with an object_name and schema so it points to a feature class, I can get layer properties from Describe and use things like ListFields(). So I know it can make some kind of usable connection. When testing, I'm only specifying database_platform, instance, username, and password. Is there something I'm doing wrong?
