Comment (by raydeal):
This error is because JSON is stored in NCLOB database type but according
to Oracle documentation:
Oracle Database does not support constraints on columns or attributes
whose type is a LOB, with the following exception: NOT NULL constraints
are supported for a LOB column or attribute.
The exact check should be implemented differently to work with JSON in
LOB. I am working on it.
