Fails to pull from/save to yml files on 1.21.3?

[GentlemanCheesy]

On 1.21.3 the plugin leaves a bunch of errors in console and cannot use/make yml files.

Example of this as a snippet of my latest logs: https://pastebin.com/pXhqh1hi

Paper Version 1.21.3
Skript version 2.9.4

Hello, I spoke with the developer, part of it is an issue with skript-yaml itself while the other part is an issue with my fork. I plan on fixing it in the coming days. You can view the entire conversation here

Not sure its the same issue but if you can reproduce this error can you send me the yaml file so I can test on my end? It appears to be tripping within snakeyaml

function createbpdata(p:player):
	load yaml "plugins/.data/backpack/%uuid of {_p}%.yml" as "bp.%uuid of {_p}%"
	yaml path "data.name" in "bp.%uuid of {_p}%" does not exist
	set yaml value "data.name" from "bp.%uuid of {_p}%" to name of {_p}
	save yaml "bp.%uuid of {_p}%" with an indentation of 2

command /backpack:
	trigger:
        	createbpdata(player)
        	set metadata tag "bp" of player to chest inventory with 3 row named "&cBackpack"
        	loop 29 times:
            		set slot (loop-value-2)-1 of metadata tag "bp" of player to yaml value "data.%loop-value-2%" from "bp.%uuid of player%"
        	open metadata tag "bp" of player to player
    
on inventory close:
    event-inventory = metadata tag "bp" of player
    loop 27 times:
        set yaml value "data.%loop-value%" from "bp.%uuid of player%" to slot (loop-value)-1 of event-inventory
    save yaml "bp.%uuid of player%" with an indentation of 2

its just a simple backpack skript though, nothing fancy, but yeah i shouldve saved each slot in a separate yml instead in 1 file, so that if its start throwing errors my players wouldnt have to lose an entire chest of items
