code used to add entry

Code (CSharp):

1. AddressableAssetSettings settings = AddressableAssetSettingsDefaultObject.Settings;
2. AddressableAssetGroup group = settings.DefaultGroup;
3. List<AddressableAssetEntry> list = new List<AddressableAssetEntry>();
4. AddressableAssetEntry e = settings.CreateOrMoveEntry(guid, group , false , true);
5. settings.SetDirty(AddressableAssetSettings.ModificationEvent.EntryMoved , e , true);

in set dirty method i try to pass list of one entry as "eventData" and i change modification event addedEntry but still dosnt work.
when i add addressableentry via editor everythink is working

Unity 2019.30f3 addressables 1.6

thank you for help, and sorry for poor grammar

 

Code (CSharp):

1.  
2.                     string name = "chunk [" + vec + "]";
3.                     GameObject gm = new GameObject();
4.                     gm.name = name;
5.                     string path = prefabFolder + "/" + name + ".prefab";
6.                     PrefabUtility.SaveAsPrefabAsset(gm, path , out bool succes);
7.                     if ( ! succes)
8.                     {
9.                         Debug.LogWarning("ops");
10.                         return;
11.                     }
12.                     string guid = AssetDatabase.AssetPathToGUID(path);
