%player_name% and %player% not replaced by the player's name. | HelpChat | Page 1

Hello, I have a problem with the placeholder API plugin (version 2.11.4) and Paper-196 (MC: 1.20.1). I also use several other plugins, such as essentialsX, eco, boosters, vault, and essentialsSpawn. I'm having a problem with the Boosters plugin, so here's what I want to do: basically, the plugin is designed to create boosters, so you can execute commands when a booster is active and when it's deactivated. To do this, I use the %player% placeholder, for example ; give %player% diamond 64. With the placeholderAPI plugin, the %player% placeholder is not replaced by the player's name, but by empty space. As a result, none of the commands work, and when I remove the placeholderAPI plugin, the player's name is recognized, so what can I do?
I've also downloaded the expansion player via /papi ecloud download player.
Even if I replace %player% with %player_name%, it still doesn't work, it's not replaced by the player's name.

#%player_name% and %player% not replaced by the player's name.
