How to access nodes and their metadata in dialogue?

[AngryApple5000]

I created a metadata string called "name" inside the player model. I am trying to get the Player node (accessed via unique name %), the name string and it's value in the dialogue to have different speech based on the value, like in the code below.

if %Player.get_meta("name") == "Nothing": TestPerson: Who are you?

I am getting the error show_error_for_missing_state_value: Assertion failed: "Player" not found. States with directly referenceable properties/methods/signals include "{ "self": }", "Balloon", "Game". Autoloads need to be referenced by their name to use their properties.

Please help I am struggling to figure out how to do this and I am fairly new to Godot
