ORA-61769
'keyColumn' values specified in the metadata are not valid for native collection.
Cause
Values set under 'keyColumn' are incompatible with native collection.
Action
When 'native' is set to true, omit all other metadata fields. If you specifiy 'keyColumn' value explicitly, they must be the following: 'keyColumn.name' is OBJECT_RESID, keyColumn.type is RAW, 'keyColumn.assignmentMethod' is EMBEDDED_OID, and 'keyColumn.path' is _id. If omitted, they will be defaulted to these values.
