Question
I am trying to add importing of a filetype to my plugin but even after following the tutorial and looking around, I have ended up with the error
Error importing 'res://SavedDialogueScenes/TestExport.ds'.
I think everything else in the script file is correct but I am completely unsure and have no possible idea for why this may be happening 
.

@tool
extends EditorPlugin
var editor = preload("res://addons/DialogueSystem/DialogueEditor/DialogueEditor.tscn").instantiate()
