ORA-61770
'contentColumn' values are not valid for native collection.
Cause
Values set under 'contentColumn' field are incompatible with native collection.
Action
When 'native' is set to true, omit all other metadata fields. If you specify 'contentColumn' values explicitly, they must be the following: 'contentColumn.name' is DATA and 'contentColumn.type' is JSON. If omitted, they will be defaulted to these values.
