Hi, This configuration seems to work on my side with paper 1.21.4
What server version and firmware are you using ? (for example, paper 1.21.4) (use /version in server)
Is there any error or info log created by CustomAnvil at startup ?

Also, seems like the provided error do not have stack trace. Did you disable it somehow ?
If it is indeed disabled and you know how to re-enable it on your side I recommend doing it (at least temporarily), try to use the anvil, and then sending me the stack trace of the error as it would allow me to find more easily the cause of the problem

Also, do you have any other plugin that may impact the anvil mechanic ?

im using divinemc 1.21.3 build 418, the custom anvil mechanic work just fine

it trigger error whenever an armor or anything item has EnchantsSquared enchant on, and try to put into the anvil (in my test i always put to slot 1)

i didnt do anything about stack trace, it just like that somehow which im also confused

sometime it also trigger rename error cuz str is null or something (i was lowering custom anvil version from 1.7.0 to 1.6.13 and disenchant to 5.x cuz i thought it could fix this i guess im wrong)

i have other plugin related to anvil named Geyser Recipe Fix, but that error was happen when testing on java so i dont think it related (i didnt test on geyser/bedrock tho)

[alexcrea]

I found the reason of the second issue, but first one, still have no idea why
as by your description it seems to only happen with enchantment squared, I just will make more safeguard & proper error log to be safe. So I will soon give you a jar that should at least help debug the issue.
btw, could not still reproduce the issue on my side sadly

[alexcrea]

could you test with https://github.com/alexcrea/CustomAnvil/releases/tag/v1.7.1-test1 ?

[cupang-afk]

could you test with https://github.com/alexcrea/CustomAnvil/releases/tag/v1.7.1-test1 ?

i can confirm this doesn't trigger the log error anymore (including the first one)

Oh ? I guess the first issue has the same cause as the same as the second one. Just stack trace somehow did not get printed
I will be uploading the version or spigot, modrinth, hangar later
