Different internal and RestApi model for folder.

Do not use the repository folder model for the ProtectedDataController:

pServer/src/ItspServices.pServer/Controllers/ProtectedDataController.cs

Lines 29 to 32 in b5de60a

    
           public Task<Folder> GetFolderById(int? id) 
        
           { 
        
               return Task.FromResult(_repository.ProtectedDataRepository.GetFolderById(id)); 
        
           }

If you do so, you can omit the id of the just requested folder, because there is no point in delivering the data you just provided.
In order to make it working you need to remove the two following asserts

pServer/test/ItspServices.pServer.Test/AuthorizedEnpointTest.cs

Line 180 in b5de60a

Assert.AreEqual(token["id"].Value<int>(), 0);

pServer/test/ItspServices.pServer.Test/AuthorizedEnpointTest.cs

Line 192 in b5de60a

Assert.AreEqual(token["id"].Value<int>(), 1);

You also can add values that does not exist in the repository folder model e.g. full qualified name etc.

	public Task<Folder> GetFolderById(int? id)
	{
	return Task.FromResult(_repository.ProtectedDataRepository.GetFolderById(id));
	}
