no error event on subcommand precondition

what event fires when a Subcommand's precondition (on a subcmd, not the whole class) fails? i'm not getting it to SubcommandError or commandDenied

andi know for a fact the precondition returns an error, i checked that and the command config

SubcommandPluginEvents.ChatInputSubcommandError does not emit denied precondition, SubcommandPluginEvents.ChatInputSubcommandDenied is what you are looking for

oh that's a mess so -Error emits errors for decorators but -Denied emits errors for preconditions šŸ˜­
Oreo ā„¢
Oreo ā„¢ā€¢6mo ago
no? Error emits Errors and Denied emits Precondition deny payloads makes sense to me bc preconditions deny a command from functioning if it "fails"

Preconditions run before the command, they are PRE conditions. Decorators however with how they're implemented in TypeScript they run when the function runs and call function.apply to run the normal functionality after finishing the decorator but by that point the function itself is already running, it's no longer PRE function.
