Can't filter task list based on group name

As per the current code implementation, I can't be able to filter task list based on user group passed in the kie server pot-owners API.

I looked at the code, we are not using the group name which passed in the API while filtering task list,
Current Code:
@Override
public List getTasksAssignedAsPotentialOwner(String userId, List groupIds, QueryFilter filter)

{ Map<String, Object> params = new HashMap<String, Object>(); params.put("userId", userId); params.put("groupIds", mergeLists(groupIds, getCallbackUserRoles(userGroupCallback, userId))); applyQueryContext(params, filter); applyQueryFilter(params, filter); return (List) commandService .execute(new QueryNameCommand<List>("TasksAssignedAsPotentialOwnerWithGroups", params)); }

public static List getCallbackUserRoles(UserGroupCallback userGroupCallback, String userId) {
List roles = userGroupCallback != null ? userGroupCallback.getGroupsForUser(userId) : new ArrayList<>();
if (roles == null || roles.isEmpty())

{ roles = new ArrayList<>(); roles.add(""); }

return roles;
}

But the actual code will be look like below,

@Override
public List getTasksAssignedAsPotentialOwner(String userId, List groupIds, QueryFilter filter) {
Map<String, Object> params = new HashMap<String, Object>();
// params.put("groupIds", mergeLists(groupIds, getCallbackUserRoles(userGroupCallback, userId)));
if (groupIds == null || groupIds.isEmpty())

{ params.put("userId", userId); params.put("groupIds", getCallbackUserRoles(userGroupCallback, userId)); }

else
params.put("groupIds", filteredUserGroups(groupIds, getCallbackUserRoles(userGroupCallback, userId)));
applyQueryContext(params, filter);
applyQueryFilter(params, filter);
return (List) commandService
.execute(new QueryNameCommand<List>("TasksAssignedAsPotentialOwnerWithGroups", params));
}

private List filteredUserGroups(List groupIds, List callbackUserRoles) {
List data = new ArrayList();
for (String groupId : groupIds)

{ if (callbackUserRoles.contains(groupId)) data.add(groupId); }

return data;
}
