(Narsilion) Problem opening NPC’s equipment GUI

[viscid trench]

Apologies if this has already been tackled.
My server is 1.18.2,on arclight,I added mods and plugins .
Everything is normal until I tried to change the NPC's equipment by using command '/npc equip',gui opened but my inventory has become empty.I checked Wiki but I didn't find out why, maybe it's due to a version error?
Please help me fix it

Info: forks

Our plugins (Citizens, Sentinel, and Denizen) officially support both Spigot and Paper.
Any other forks of the Bukkit project are not supported, but may or may not work in practice.

• Lower forks, like CraftBukkit, do not function. You must upgrade to a higher fork (Spigot or Paper).

• Hard forks and cross-forks, like Cauldron/Magma/Mohist/Any other Forge-integration fork, or Cardboard/any other Fabric-integration fork, will not work. Some unofficial custom builds of Citizens are made to support these servers, but we cannot provide any support for them here.

• Higher forks above Spigot/Paper, such as Purpur, Airplane, etc. are compatible with Citizens only as much as they are compatible with Spigot/Paper. They are generally expected to work in most cases, but we cannot make any guarantees. We will still offer support to users running such forks, but be aware that if you encounter bugs while running such a fork, we may ask you to replicate them on Spigot/Paper to confirm they aren't caused by changes the fork made.

Hybrid server software such as arclight is entirely unsupported - it makes major changes to NMS which breaks Citizens entirely

If you can replicate your issue on supported software (Paper/Spigot) we can look into it, otherwise there's not much we can do as hybrid server softwares break too much
