TypeError: Cannot read property 'id' of undefined

[ProCoda]

It says the error is coming from the line: const existing = this.groups.get(group.id);

Nevermind, I just made a stupid error in index.js. That fixed my problem, but I dont really know if it will fix yours.

        ['mod', 'Group for moderation'],
])
