Dialogue Manager Addon bug

[night spindle]

I recently installed an addont for a project, which was Nathan Hoad's Dialogue Manager addon for Godot 4.0. When I correctly installed and called the addon's autoload node to show a dialogue bubble, I kept getting this error without any knowledge as to what caused it, or how I can fix it. I have no idea if this is cause of me messing with the grab focus functions of other ui elements in my project, or if this is an actual bug in the plugin I need to try and fix. If somebody could help me out here, I would greatly appreciate it, because I am absolutely not in the mood to be dealing with this error for another hour.

I already tried to manually set the focus mode of the balloon in-question, and the error still persisted

The "balloon" variable is null. Which means it has not been set to anything.

The example balloon scene that addon comes with should be set up correctly. Did you edit it?
From memory, the root node is a canvas later, and the first child is the balloon node in question

the balloon node is still fine in the script - it's being called as an onready variable, and i still dont really understand why the variable would end up being null in the first place

i am actively trying different ways to define the node but for some reason it always gets reset to null
