Invalid configuration error

I have the latest version of pufferpush skills and pufferpush attributes on Minecraft 1.20.1 Forge and datapack installed but I get this error and the pufferpush skill tab shows "There doesn't seem to be anything here...".

If you are sure everything is installed correctly, then please send the game logs. You can alternatively try to install Default Skill Trees mod instead of a data pack.
