Error in GXDLMSTokenGateway when executing action enter(data)

Good morning!

First of all, thank you in advance for any reply. I have developed a device simulator using Gurux as a server.

I'm trying to execute the action defined in the bluebook as enter(data)

protected override void PreAction(ValueEventArgs[] args)
{
foreach (var valueEventArg in args)
{
Logger.Information("{Method} {Target}:{LogicalName}", nameof(PreAction), valueEventArg.Target.GetType(),
valueEventArg.Target.LogicalName);
_companionServer.CompanionPreAction(valueEventArg, this);
}
}

------------------------------------------------------------------

public void CompanionPreAction(ValueEventArgs preActionArgs, DlmsServer dlmsServer)
{
switch (preActionArgs.Target)
{
case GXDLMSImageTransfer _:
HandleImageTransferActions(preActionArgs);
break;
case GXDLMSSecuritySetup _:
HandleSecuritySetupActions(preActionArgs);
break;
case GXDLMSClock _:
HandleClockRelativeTimeSetActions(preActionArgs);
break;
case GXDLMSDisconnectControl _:
HandleDisconnectControlActions(preActionArgs, dlmsServer);
break;
case GXDLMSTokenGateway _:
HandleTokenGatewayActions(preActionArgs);
break;
}
}

------------------------------------------------------------------

When it arrives to the server I try to assign the value of the structure in the response and I get no result.

1. If I just assign the value to the token it returns success but no data.

protected void HandleTokenGatewayActions(ValueEventArgs preActionArgs)
{
if (!(preActionArgs.Target is GXDLMSTokenGateway gxdlmsTokenGateway)) return;

switch (preActionArgs.Index)
{
case 1:
{
gxdlmsTokenGateway.Token = (byte[])preActionArgs.Parameters;

preActionArgs.Handled = true;

break;
}
}
}

2. If I try to assign the value of the attribute with the GetValues I get a ReadWriteDenied error.

protected virtual void HandleTokenGatewayActions(ValueEventArgs preActionArgs)
{
if (!(preActionArgs.Target is GXDLMSTokenGateway gxdlmsTokenGateway)) return;

switch (preActionArgs.Index)
{
case 1:
{
gxdlmsTokenGateway.Token = (byte[])preActionArgs.Parameters;
gxdlmsTokenGateway.StatusCode = TokenStatusCode.TokenExecutionOk;
gxdlmsTokenGateway.DataValue = Convert.ToString((byte)(101));

preActionArgs.Value = gxdlmsTokenGateway.GetValues()[5];

preActionArgs.Handled = true;

break;
}
}
}

3. If I try to assign a structure it also gives an error ReadWriteDenied

protected virtual void HandleTokenGatewayActions(ValueEventArgs preActionArgs)
{
if (!(preActionArgs.Target is GXDLMSTokenGateway gxdlmsTokenGateway)) return;

var structure = new GXStructure
{
(byte)gxdlmsTokenGateway.StatusCode,
gxdlmsTokenGateway.DataValue
};

preActionArgs.Value = structure;

preActionArgs.Handled = true;

break;
}
}
}

4. On the other hand, if I assign a string it returns an OctetString, but of course this is not what the client system expects.

protected virtual void HandleTokenGatewayActions(ValueEventArgs preActionArgs)
{
if (!(preActionArgs.Target is GXDLMSTokenGateway gxdlmsTokenGateway)) return;

var buff = new GXByteBuffer();
buff.SetUInt8((byte)DataType.Structure);
buff.SetUInt8((byte)2);
SetData(new GXDLMSSettings(), buff, DataType.Enum, (object)gxdlmsTokenGateway.StatusCode);
SetData(new GXDLMSSettings(), buff, DataType.BitString, (object)gxdlmsTokenGateway.DataValue);
var result = (object)buff.Array();

preActionArgs.Value = result;

preActionArgs.Handled = true;

break;
}
}
}

Can someone help me? I am desperate. Thanks again for your trouble.
