Description
When i type: /give Mini_The_MB bluepaint it doesn't give me anything, and the chat also says nothing.

Steps to reproduce
I typed /give Mini_The_MB bluepaint

Expected behavior
I expected the custom_items.yml to give me blue_dye. It's the same for snad: sand and breakfast: cooked_porkchop.. A link to my file, in case you'll need a look: I https://gist.github.com/MiniTheMB/3e216c9e8bce3d5c17c1be73193d3f16 I haven't changed anything in the file, this is what essentials give me.

Screenshots
My chat don't say anything, and the console is up above :D

I can reproduce this bug on the following:

[01:57:38 INFO]: Server version: 1.15.2-R0.1-SNAPSHOT git-Paper-98 (MC: 1.15.2)
[01:57:38 INFO]: EssentialsX version: 2.17.1.61
[01:57:38 INFO]: LuckPerms version: 5.0.39
[01:57:38 INFO]: Vault version: 1.7.2-b107

Below is the same error output with debug enabled:

It appears that the custom item resolution process triggers an infinite loop which causes the bug to occur.

This has now been fixed - you can download the latest version from the build server.
