It seems that you are trying to use IgniteRepository to work with a JPA entity.
I don't think that it's possible to marry these two. Spring JPA chokes on IgniteRepository custom methods trying to convert them into SQL, and even if it didn't it would still not work.
IgniteRepository was just not designed for JPA.
