I published GrandNode on Linux Server as Master Tenant then I created a new tenant with name Tenant1.
I am getting this msg in Tenant1 instance:

An unhandled exception occurred while processing the request.
DirectoryNotFoundException: Could not find a part of the path '/var/aspnetcore/qa.Naadel/wwwroot/Tenant1/assets/images/flags'.
System.IO.Enumeration.FileSystemEnumerator<TResult>.CreateDirectoryHandle(string path, bool ignoreNotFound)

when I click on English language to edit it in Configuration --> Languages.
I Know that when I created the new tenant tenant1 it will create and folder in wwwroot with name Tenant1 inside this folder there will be images folder but inside this images folder there is no flags folder, icons folder, and no-image.png.

so is there any problem with creating new tenant process ?

Thanks a lot for the report. This is definitely an issue. Here is the work item.

@Yousef,

We've fixed the issue and released a new 1.0.1 version, you can download it and update your store :)
