How to get the key of a data store?

I'm trying to use the datastore editor plugin to edit a player's datastore, but when I try and use the player's id as the key, it doesn't work. No data comes up.

Probably becuase you don't have any data saved in that data store?

First, you have to check if the game is saving the data. If it is, the data could have corrupted or the plugin doesn't work.
