onCommandError property

A stream of CommandsExceptions that occur during a command's execution.

Any error that occurs during the execution of a command will be added here, allowing you to respond to errors you might encounter during a command's execution. Notably, CheckFailedExceptions are added to this stream, so you can respond to a failed check here.

CommandsErrors that occur during the registration of a command will not be added to this stream, now will any object thrown that is not an Exception.

Exceptions thrown from within a command will be wrapped in an UncaughtException, allowing you to access the context in which a command was thrown.

By default, nyxx_commands logs all exceptions added to this stream. This behavior can be changed in options.

• CommandsException, the class all exceptions in nyxx_commands subclass;
• CallHooked.onPostCall, a stream that emits CommandContexts once a command completes successfully.
