Spring repository filter with specification Blob column, which string array in java

Question

i have BLOB column in Mysql database.

In java this column parsed as string array:

    @Column(
    name = "categories",
    nullable = false,
    length = 2048
)
private String[] categories;

This class have spring repository method findAll which uses predicates from Specification for filtering:

    Page<Campaign> findAll(Specification<Campaign> spec, Pageable pageable);

For colum with type String we create predicate with next code example:

    public static <T extends AbstractPersistable> Predicate likeLower(Root<T> root, CriteriaBuilder cb, String name, String value) {
    if (isBlank(value)) {
        return null;
    }
    return cb.like(cb.lower(root.get(name)), '%' + value + '%');
} 

im create predicate with code below : predicates.add(likeLower(root, cb, "categories", filterCategories));

When i run query SELECT * FROM persona_adserver.campaign where categories like '%asino%'; in mysql directly i receive 209 rows as result.

But when i pass predicate to repositoy i have exception:

org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [%asino%] did not match expected type [[Ljava.lang.String; (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [%asino%] did not match expected type [[Ljava.lang.String; (n/a)]

Update 1

filterCategories comes from api request as String param
