Value does not fall within expected range in client object model SharePoint online

Question

Hi,
I might be missing something, at least i hope so because I don't see it anymore.
Yes, I used the search, and yes many had the same error, but I think my problem has to be something else.
It is not size related but more context related i think.
I've build a function to break inheritance on folders and libraries for several document librarys to implement a crud matrix.
The thing is, it works sort of. The function takes a list and foldername. If the foldername is null the
inheritance on the list is broken and the group is given the roles as provided.
If a foldername is given, i retrieve the folder, break the inheritance and set the new permissions for the given group.
The problem is: The second time the function is called with a foldername it breaks on the getItems for querying the folder.
It is not folder related, becaus changing the folder order gives the same problem on another folder.
I already tried creating a new clientcontext and a new list variable but i cant get it to work.
I cant get into the server logs because im querying SharePoint Online.
var list = GetList(clientContext, "Listx");
AddPermission(list, null, company_Groups.Beheerder, RoleType.Contributor, clientContext);
AddPermission(list, null, company_Groups.Projectleider, RoleType.Contributor, clientContext);
AddPermission(list, null, company_Groups.Constructeur, RoleType.Reader, clientContext);
AddPermission(list, null, company_Groups.Tekenaar, RoleType.Contributor, clientContext);
//Montagepartner
AddPermission(list, "Folder2", company_Groups.Montagepartner, RoleType.None, clientContext);
AddPermission(list, "Folder1", company_Groups.Montagepartner, RoleType.None, clientContext);         <----- is where it breaks
AddPermission(list, "Folder3", company_Groups.Montagepartner, RoleType.None, clientContext);
AddPermission(list, "Folder4", company_Groups.Montagepartner, RoleType.None, clientContext);
private void AddPermission(List list, string folderName, company_Groups group, RoleType roleType, ClientContext clientContext)
//MsOnlineClaimsHelper claimsHelper = new MsOnlineClaimsHelper();
//using (ClientContext clientContext = new ClientContext(ctx.Url))
//clientContext.ExecutingWebRequest += claimsHelper.clientContext_ExecutingWebRequest;
//clientContext.RequestTimeout = timeOut;
if (!list.HasUniqueRoleAssignments)
list.BreakRoleInheritance(false, true);
list.Update();
var principal = GetPrincipal(clientContext, group.ToString());
var role = GetRole(clientContext, roleType);
// Add the role to the collection.
//var collRdb = new RoleDefinitionBindingCollection(clientContext) { role };
if (folderName != null)
var query = new CamlQuery();
query.ViewXml = "<View Scope=\"RecursiveAll\"> " +
 "<Query>" +
  "<Where>" +
  "<And>" +
"<Eq>" +
  "<FieldRef Name=\"FSObjType\" />" +
  "<Value Type=\"Integer\">1</Value>" +
"</Eq>" +
"<Eq>" +
  "<FieldRef Name=\"Title\"/>" +
  "<Value Type=\"Text\">" + folderName + "</Value>" +
"</Eq>" +
  "</And>" +
  "</Where>" +
  "</Query>" +
  "</View>";
// query.FolderServerRelativeUrl = Path.Combine(list.RootFolder.ServerRelativeUrl, folderName);
///This is where it breaks, the second time the function executes on a list with another folder name
var folderItems = list.GetItems(query);    <----- is where it breaks 
clientContext.Load(folderItems);
clientContext.ExecuteQuery();
ListItem folder = null;
if (folderItems.Count > 0)
folder = folderItems[0];
folder = list.GetItemById(folder.Id);
//if (!folder.HasUniqueRoleAssignments)
folder.BreakRoleInheritance(true, true);
folder.Update();
RoleDefinition roledef = clientContext.Web.RoleDefinitions.GetByType(roleType);
RoleDefinitionBindingCollection roleDefCol = new RoleDefinitionBindingCollection(clientContext);
// .Add(roledef);
roleDefCol.Add(roledef);
folder.RoleAssignments.Add(principal, roleDefCol);
folder.Update();
else
RoleDefinition roledef = clientContext.Web.RoleDefinitions.GetByType(roleType);
RoleDefinitionBindingCollection roleDefCol = new RoleDefinitionBindingCollection(clientContext);
// .Add(roledef);
roleDefCol.Add(roledef);
list.RoleAssignments.Add(principal, roleDefCol);
list.Update();
clientContext.ExecuteQuery();

Hi,                                                             
What if you execute the AddPermission method once a time, will the error still occur or can your code works out the expected result?
As the program breaks in the GetItems() method, to narrow down this issue, I suggest to comment the other lines of code which has no relationship with the items retrieving, then debug your project to see whether the error will
still occur.
