upload entities from one account to another in same title

Hey,

I am trying to get entities from one account and upload it to another.

i am using two different entity tokens, and my error is -

"The claim was not allowed to perform the requested action based on the entity's access policy."

this is my policy:

[
  {
    "Action": "*",
    "Effect": "Allow",
    "Resource": "*--*",
    "Principal": {
      "ChildOf": {
        "EntityType": "namespace",
        "EntityId": "E1C86539AD904942"
      }
    },
    "Comment": "The default allow title in namespace full access",
    "Condition": {
      "CallingEntityType": "title"
    }
  },
  {
    "Action": "*",
    "Effect": "Allow",
    "Resource": "pfrn:data--*![SELF]/Profile/*",
    "Principal": "[SELF]",
    "Comment": "The default allow profile self access",
    "Condition": null
  },
  {
    "Action": "*",
    "Effect": "Allow",
    "Resource": "pfrn:data--*![SELF]/Profile/*",
    "Principal": {
      "ChildOf": {
        "EntityType": "[SELF]"
      }
    },
    "Comment": "The default allow profile child access",
    "Condition": null
  },
  {
    "Action": "Write",
    "Effect": "Deny",
    "Resource": "pfrn:data--*!*/Profile/Statistics/*",
    "Principal": "*",
    "Comment": "Only title can edit user statistics",
    "Condition": {
      "CallingEntityType": "title_player_account"
    }
  },
  {
    "Action": "Write",
    "Effect": "Deny",
    "Resource": "pfrn:data--*!*/Profile/Statistics/*",
    "Principal": "*",
    "Comment": "Only title can edit user statistics",
    "Condition": {
      "CallingEntityType": "character"
    }
  },
  {
    "Action": "Write",
    "Effect": "Deny",
    "Resource": "pfrn:data--*!*/Profile/Statistics/*",
    "Principal": "*",
    "Comment": "Only title can edit user statistics",
    "Condition": {
      "CallingEntityType": "master_player_account"
    }
  },
  {
    "Action": "Write",
    "Effect": "Deny",
    "Resource": "pfrn:data--group!*/Profile/Statistics/*",
    "Principal": {
      "MemberOf": {
        "RoleId": "*"
      }
    },
    "Comment": "Only title can edit group statistics",
    "Condition": null
  }
]

not sure what i need to edit here and why, this is my code:

var request = new GetFilesRequest { Entity = oldEntityToken };
        PlayFabDataAPI.GetFiles(request, (OnGetFileMeta) =>
        {
            try
            {
                PlayFabHttp.SimpleGetCall(OnGetFileMeta.Metadata[PLAYER_ENTITIES_KEY].DownloadUrl,
                    (OnGetFileFinished) =>
                    {
                        UploadEntities(OnGetFileFinished, newEntityToken);
                    }, (error) =>
                    {
                        Debug.LogError(string.Format("GetPlayerEntitesByEntityTokenAndUploadToNewEntityToken + {0}", error));
                    });
            }
            catch (Exception)
            {
                Debug.LogError("GetPlayerEntitesByEntityTokenAndUploadToNewEntityToken - GetOldAccountData - faild");
            }
        }, (OnInitFailed) =>
        {
            Debug.LogError(string.Format("GetPlayerEntitesByEntityTokenAndUploadToNewEntityToken - OnInitFailed + {0}", OnInitFailed.ErrorDetails));
        });

Upload Entities:

  public static void UploadEntities(byte[] payload, PlayFab.DataModels.EntityKey EntityToken)
    {
        try
        {
            InitiateFileUploadsRequest initiateFileUploadsRequest = new InitiateFileUploadsRequest()
            {
                Entity = EntityToken,
                FileNames = new List<string>() { PLAYER_ENTITIES_KEY }
            };


            PlayFabDataAPI.InitiateFileUploads(initiateFileUploadsRequest, (response) =>
            {
                PlayFabHttp.SimplePutCall(response.UploadDetails[0].UploadUrl, payload, (byteArray) =>
                {
                    FinalizeFileUploadsRequest finalizeFileUploadsRequest = new FinalizeFileUploadsRequest
                    {
                        Entity = EntityToken,
                        FileNames = new List<string>() { PLAYER_ENTITIES_KEY }
                    };


                    PlayFabDataAPI.FinalizeFileUploads(finalizeFileUploadsRequest, (OnUploadSuccess) =>
                    {
                        isMergeEntitesDone = true;
                    }, (OnSharedFailure) =>
                    {
                        Debug.Log(OnSharedFailure);
                    });
                },
                    (OnSharedFailure) =>
                    {
                        Debug.Log(OnSharedFailure);
                    });
            }, (OnInitFailed)=> 
            {
                Debug.LogError(OnInitFailed);
            });
        }
        catch (System.Exception ex)
        {
            Debug.LogError(ex.InnerException);
        }
    }
