JPA createQuery with passing list as parameter when the list is null or empty

Question

I am trying to create the query with join in multiple tables and passing lists as parameters. I am putting the null & empty check within the query string. However i am getting NullPointerException on QueryNode.getDataType. Below are the query and the exception.

    query = em.createQuery("select avg(kpi.duration), kpi.taskId from KPI kpi, User user, UserRole userRole, Shop shop where " +
            "(user.clientId = :customer or :customer is null) and (kpi.userId in :users or :users is null or :users = '' ) and " +
            "(userRole.role in :roles or :roles is null or :roles = '') and (shop.shopName in :shopNames or :shopNames is null or :shopNames = '') " +
            "and kpi.userId = userRole.userId and kpi.userId = user.id and kpi.userId = shop.userId group by kpi.taskId");

    query.setParameter("customer",customer);
    query.setParameter(“users”,users);
    query.setParameter(“roles”,roles);
    query.setParameter("shopNames", shopNames);

    if (query != null){
        List result = query.getResultList();
}

users, roles & shopNames are lists and customer is string. I have created queries pereviously with only strings with the null check and it worked. However, with lists, it errored out with the below. Any suggestion how to do it without checking for each parameter in a if else logic.
