4 days ago I figured out what's happening, paper started to use mojang mapping instead of spigot mapping after 1.20.5, which makes my plugin (using spigot mapping names) can't properly use NMS with reflections, so there are few options:
-
Don't use paper server, use spigot
-
I manually add every mojang mapping name (of fields methods classes...) to the code
-
Other black magic to solve this (I didn't find it yet)
The first 2 options are for you if you really want to use CustomSprays plugin really quick, but I will definately find a way to make a universal plugin for both spigot & paper

In the latest 1.21 version on a 1.20.6 server, the plugin will be disabled on launch without any error in the server, if i try to use the command/s in game an error occurs telling me the plugin is disabled. If i go back one plugin version i get an error on load up and the server shows it was disabled.
If you have any issues understanding anything i have typed, do not hesitate to ask for help understanding.
Error for 1.21(latest) version
