Which data package do you need?

at 9 pm when I wanted to start the server I saw that in the log and I don't know exactly what happened.

i am playing in a server with some friends with 7 plugins in paper mc latest version and i don't want to lose the world because we have a lot of things, what can i do?.

sorry if I'm misspelling some things I'm using translator.

So far I do not have any data packs

There it is I managed to solve it one of the op had put the datapack disable vanilla and I managed to solve it by copying all the files of the world to another world.
