**Expected behavior**
Plugin showing enderchest holograms without warns.

Hello! EnderContainers does not officially support Purpur: this feature uses internal classes to operate and this may not work for a Bukkit/Spigot fork. But as this is a drop-in replacement for Paper, I will quickly check if I can find a working code for both Bukkit/Purpur

[utarwyn]

Oh this bug also occurs on Bukkit 1.19.3 / 1.19.4. I didn't think it could happen with the same minor version.. but since Minecraft's network protocol changes between patch versions, it broke my integration... I am working on a fix.

[utarwyn]

Hello @denvolj, support for Minecraft 1.19.3/1.19.4 has been added to the plugin! (v2.2.3 and v2.3.0) This should also work for Paper/Purpur. Feel free to reopen the issue if the bug persists.
