Description

Whenever I try to get a metadata from an offline player with no matter GameProfile or UUID, it just left me a NullPointerException.

Reproduction Steps

// source instanceof CommandSourceStack && source.isPlayer()
Options.get(source.getPlayer().getGameProfile(), "foo").join()

Result:

java.util.concurrent.CompletionException: java.lang.NullPointerException: Cannot invoke "java.util.Optional.isPresent()" because "value" is null

Expected Behaviour

Return me anything but a null. :(

Extra Details

This glitch seems exist from at least MC 1.21.1?

are you actually loading the user? you must load the user first

are you actually loading the user? you must load the user first

@BNTFryingPan Excuse me, I don't actually know what is loading a user. I didn't find any introductions in fabirc-permission-api

Being tested:

Permissions.check(source.getPlayer().getGameProfile(), "foo").join(); // Success
Options.get(source.getPlayer(), "foo").join(); // Success
Options.get(source.getPlayer().getGameProfile(), "foo").join(); // NullPointerException

you must use the LP api directly if you want to get data about offline players

@BNTFryingPan
May I ask why? It seems that getting data from offline player with farbic permission api has already been implemented. It just not works.

Okay, I see. This is caused by an unexpected null in farbic permission api.

Thank you for your help anyway. I'll later fix it.
