CommandKit is the discord.js meta-framework for building Discord bots. In versions 1.2.0-rc.1 through 1.2.0-rc.11, a logic flaw exists in the message command handler that affects how the commandName property is exposed to both middleware functions and command execution contexts when handling command aliases. When a message command is invoked using an alias, the ctx.commandName value reflects the alias rather than the canonical command name. This occurs in both middleware functions and within the command's own run function. Although not explicitly documented, CommandKit's examples and guidance
