Hello, I'm using spring data JDBC to manage two entities, but I am getting a rather strange exception when testing the UserRepository. Spring is trying to map the "users_key" attribute of the "expense" table, but this attribute is nonexistent. I'm sure the core problem is in the mapping of the "expense" attribute of the User entity, because when I annotate the attribute as @Transient, the exception doesn't occur.
Below are the images of the entities, the SQL script to generate the tables, the test code, the repository and the stack trace
