Are you shading the CommandAPI?
No
What I did
- I created a command using a CustomArgument and a StringArgument (the second one has suggestions).
ArgumentSuggestions suggestFoo = (i, b) -> b.suggest("foo").buildFuture();
ResultingCommandExecutor executor = (sender, args) -> {
sender.sendMessage("ok");
return 1;
};
new CommandAPICommand("test_error")
.withArguments(
new CustomArgument<String, String>(new StringArgument("arg1"), info -> info.input()),
new StringArgument("arg2")
.replaceSuggestions(suggestFoo))
.executes(executor)
.register();
- Then I tried these commands:
/test_error arg1 arg2/execute run test_error arg1 arg2/execute store result score result tests run test_error arg1 arg2
What actually happened
- ✔️ These commands are executing (with command block/chat) and return 1 in the score "tests/result".
- ❌ But for the 2 last commands, I get a NullPointerException when completing the second argument.

I have tried with a CommandTree and a CommandAPICommand, the result is the same. Also this appends when there is a CustomArgument followed by any argument with suggestions.
