Hi @nargetdev,

Thank you for reaching out.

You mentioned AddTag and AddField, but these methods are not currently part of our official source base.

To better assist you and ensure you’re receiving accurate guidance, could you please share which tutorial or documentation you are following?

Looking forward to your response so we can help you.

Best Regards.

I think they just forgot to update the tutorial to current syntax.

corrected:

@nargetdev thanks for clarification. We will take a look.
